Events that could have happened but didn’t, so called counterfactual events, are but a mind-game in our reality. In quantum reality, however, they are quite real indeed. In this video I explain how this can be used to do a… Read More »Counterfactual Quantum Computation is Really Weird
Dr. Charles Adams from Durham University speaks on “Quantum semiotics” There is considerable excitement about how quantum technologies (computing, communication and sensing) could advance human well being. But, are we held back because as Richard Feynman said [1], “I think I… Read More »Quantum semiotics
Recorded 26 January 2022. Kirsten Eisentraeger of Pennsylvania State University presents “Classical and quantum algorithms for isogeny problems” at IPAM’s Quantum Numerical Linear Algebra Workshop. Abstract: Isogeny-based cryptography is one of a few candidates for post-quantum cryptography. The computational problems… Read More »Kirsten Eisentraeger on Classical and quantum algorithms for isogeny problems
Jin-Peng Liu of the University of Maryland presents “Efficient quantum algorithms for nonlinear ODEs and PDEs” at IPAM’s Quantum Numerical Linear Algebra Workshop. Abstract: Nonlinear dynamics play a prominent role in many domains and are notoriously difficult to solve. Whereas… Read More »Jin-Peng Liu – Efficient quantum algorithms for nonlinear ODEs and PDEs – IPAM at UCLA

Universal control using the quantum Zeno effect Abstract: The Zeno effect occurs in quantum systems when a very strong measurement is applied, which can alter the dynamics in non-trivial ways. Despite being dissipative, the measurement divides the Hilbert space into… Read More »Universal control using the quantum Zeno effect
For the first time in silicon, a team of engineers led by Andrea Morello at UNSW Sydney has demonstrated a three-qubit quantum processor in silicon where every operation – one-qubit logic, two-qubit logic, and qubit initialisation and measurement – is… Read More »Quantum operations with 99% fidelity – the key to practical quantum computers
This talk discusses the concept of self-testing which aims to answer the fundamental question of how do we certify proper functioning of black-box quantum devices. We will see that there is a close link between self-testing and representations of algebraic… Read More »Fixed-size schemes for certification of large quantum systems
Dr. Emily Townsend is a theoretical physicist with the University of Maryland and the National Institute of Standards and Technology. She models the physics of atom-scale devices that could become the next generation of quantum computers. This is part of… Read More »Quantum Lightning Talks: Dr. Emily Townsend
Flaviu Cipcigan of IBM research outlines the collaborative vision for how to tackle climate change. He then details the key differences between classical and QCs, and how QCs are better suited to solving inherently quantum problems related to carbon capture.… Read More »Flaviu Cipcigan Interview – Quantum Technology: Our Sustainable Future
