Date: June 7 2026 Sunday 10:00 am - Noon EDT Full title: Machine Learning for Reliable Quantum Computing: An Algorithm–Hardware Co-Design Perspective Summary: Reliable quantum computing requires co-design across the full stack, including algorithm structure, compilation, and execution, rather than isolated optimization of any single layer. This talk presents a unified framework in which these layers are jointly optimized under realistic hardware constraints. Structure-aware compilation exploits algorithmic interaction graphs to reduce circuit depth; joint optimization across mapping, term ordering, and algorithm parameters yields significantly improved success probability; and execution-layer analysis reveals that error mitigation effectiveness depends critically on circuit symmetry and native gate choice. While demonstrated on superconducting quantum processors, the underlying co-design principles are potentially transferable across architectures. Building on this foundation, the talk highlights machine learning as the key enabler for closing the feedback loop: data-efficient, parameterized noise models learned directly from workload execution data achieve substantially improved predictive fidelity over vendor models without the overhead of dedicated characterization. These insights situate the co-design perspective within the emerging framework of quantum deep learning. In this broader setting, the talk also presents an operational definition, a unifying taxonomy, and a benchmarking protocol grounded in explicit resource contracts. Speaker: Dr. Yanjun Ji has an interdisciplinary research background in Physics and Computer Science. In 2020, she completed my Master's degree in Theoretical Physics at Saarland University. In 2024, she earned her Ph.D. in Computer Science at the University of Stuttgart. She is currently a postdoctoral researcher at Forschungszentrum Jülich. She is committed to interdisciplinary research at the cutting-edge convergence of quantum computing and artificial intelligence. Her research encompasses both foundational theoretical investigations and the development of practical applications, aiming to serve society and benefit humanity.

[Profs and Pints Northern Virginia](https://www.profsandpints.com/washingtondc) presents: **“Psychedelic-Assisted Therapy,”** on findings, debates and trends in the use of psychedelic substances to treat trauma and other conditions, with Whitney Marris, instructor at the University of Buffalo’s School of Social Work, certified psychedelic-assisted therapy facilitator, and consultant to clinical trials. [Advance tickets: $13.50 plus sales tax and processing fees. Available at [https://events.ticketleap.com/tickets/profsandpints/nv-psychedelic-assisted-therapy](https://events.ticketleap.com/tickets/profsandpints/nv-psychedelic-assisted-therapy) .] Psychedelics are rapidly moving from the margins into the mainstream, and questions abound as the sociocultural and legal landscapes surrounding them shift. President Trump’s recent executive order expanding access to psychedelic drugs for certain conditions and accelerating research on them has both heightened interest and added to confusion. Learn more about the so-called “Psychedelic Renaissance,” and get help separating the hope from the hype surrounding it, with Whitney Marris, a leading trainer and facilitator of psychedelic therapy who has used it to treat trauma survivors, military veterans, and people with cancer. She’ll present foundational information on what we know about how psychedelics work. You’ll learn how psychedelic-assisted therapy differs from “trip sitting” and about what we know about the effects of “microdosing” versus “macrodosing.” We’ll examine what has been demonstrated to be helpful versus harmful before, during, and after a dosing session intended to support significant, sustainable change. Marris also will discuss the historical and cultural context of the use of psychedelic medicines for healing, and she’ll describe the ethical challenges that arise as such practices move from counterculture to clinic. We’ll look at emerging and evolving findings in the field, as well as at the roles being played by various financial interests and ideologies in determining the direction of psychedelic-assisted therapy and research on its outcomes. Attendees will gain an awareness of the need for new professional standards and regulatory guardrails related to such work, and they’ll leave knowing key questions to ask potential providers of psychedelic-assisted therapy. (Doors: $17, or $15 with a student ID. Listed time is for doors. The talk starts 30 minutes later.) Image by Canva.

[Profs and Pints DC](https://www.profsandpints.com/washingtondc) presents: **“Understanding Honor Violence,”** on recognizing and responding to harmful traditional practices that exert control over others, with Sasha K. Taylor, visiting lecturer at Ohio State University’s Global Fellowship Program and advisor and trainer in honor violence prevention. [Advance tickets: $13.50 plus sales tax and processing fees. Available at [https://events.ticketleap.com/tickets/profsandpints/dc-honor-violence](https://events.ticketleap.com/tickets/profsandpints/dc-honor-violence) .] People claiming to enforce traditional honor codes are responsible for a significant share of murders and other violent or abusive acts within immigrant and refugee communities. Honor-based violence and abuse often play a role in human trafficking, forced marriage, child marriage, visa-based coercion, and in the abandonment of families across international borders. Yet too often it is underreported, misunderstood, or overlooked by people and institutions with the power to help its victims. Learn how to spot and deal with honor-based violence with Sasha K. Taylor, a former FBI Intelligence official who provides training to law enforcement, non-profit organizations, and private companies and also is extensively involved with regional organizations that combat human trafficking. She’ll start by discussing how honor codes that have governed community life since the dawn of human civilization gave rise to the use of honor-related abuse, oppression, shame, and violence to exert control and perpetuate inequality. Although boys and men can be victims of honor-based violence, the perpetrators of it are predominantly male and the survivors predominantly female, lending support to the idea that honor violence is a form of gender-based violence. The forms that such violence can take include genital mutilation and honor killings. She’ll discuss state and federal data related to the prevalence of various forms of honor violence and describe how complex forms of abuse are often underreported, misunderstood, or overlooked. You’ll learn about cultural and systemic barriers to disclosure, warning signs and risk factors, the intersection of immigration vulnerabilities and abuse, and the challenges that survivors face when seeking protection and services. We’ll also look at policy responses to honor violence and how gaps within current federal immigration frameworks may unintentionally contribute to vulnerability and exploitation. Her talk will be especially helpful for first responders, victim advocates, educators, healthcare professionals, social workers, and law enforcement personnel who are often the first point of contact during a crisis. She’ll emphasize trauma-informed engagement, emotional intelligence, cultural competency, and empathetic response strategies that treat survivors with dignity and sensitivity.

I have been studying the question of "self" online with Prof. Ellie Anderson and so I thought a prompt on the "self" might be interesting. Full confession: I had Claude create this prompt and I like it, so here goes: Imagine a thought experiment that merges two classic puzzles: > You undergo a procedure, performed neuron by neuron, in which every biological component of your brain is replaced with a functionally identical synthetic substitute. At each step, your behavior, memories, and personality remain unchanged. When the last neuron is swapped, is the consciousness experiencing the world still you? And — more pressingly — was there ever a continuous "you" to begin with? ### Questions to Wrestle With * If consciousness is purely physical, does the *gradual* nature of the replacement matter, or is it equivalent to being destroyed and rebuilt? * Could there be a "self" without continuity of experience — even moment to moment, while you sleep? On a more practical level, consider the simpler case first: **hemispherectomy** patients — people who have had an entire cerebral hemisphere surgically removed — often retain a strong sense of personal identity and continuity. This suggests "you" are not rigidly tied to specific physical material. But does that vindicate the synthetic neuron case, or merely show that identity is more *flexible* than we thought — not that it can survive *complete* substrate replacement? I used Claude so I could get this out today and let everyone have some time to consider it. Hope to see you at the Oracle. Sorry about the location change two weeks ago. That's what I get for trusting local weather predictions!

Private Group. Closed to the Public Knowing ourselves and understanding our abilities is the first step toward wielding our gifts with control and accuracy. In subsequent classes we will verify and hone our talents with activities and discussion. These are hands-on workshops and participation is expected. The goal of our series will be to develop expertise in areas of particular interest such as mediumship, channeling, divination, healing and, etc.. Our ultimate directions will be determined by class members as we evolve. I look forward to sharing and discovering with you. - Cynthia
