Counterfactual Quantum Computation is Really Weird

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 computation without actually running the computer. This is called “counterfactual computation” (or “counterfactual quantum computation” […]

Quantum-Enhanced Markov Chain Monte Carlo Simulations with David Layden

Here’s a talk by David Layden on Quantum-Enhanced Markov Chain Monte Carlo Abstract: Sampling from complicated probability distributions is a hard computational problem arising in many fields, including statistical physics, optimization, and machine learning. Quantum computers have recently been used to sample from complicated distributions that are hard to sample from classically, but which seldom […]

Can particles really be in two places at once?

Here’s another stellar video from Sabine Hossenfelder. Today I tell you what happened when I wrote an opinion piece for the Guardian about quantum computing, had to explain what a qubit is, and decided against using the phrase that it “can be in two states at the same time”. What happened next and what did […]

Quantum Simulations of Topological Majorana Modes with Oles Shtanko

Quantum Simulations of Topological Majorana Modes Abstract: Modern quantum devices can now outperform classical computers in physical simulations, which makes them an important tool for future physics research. As an example, I will focus on simulating the topological states of matter hosting Majorana modes — the exotic “half-electron” states. Observing Majorana modes in the lab […]

From Many-Body to Many-Time Physics with Gregory A.L. White

An interesting talk on quantum correlations and how they relate to quantum computing. Abstract: Quantum correlations in time have a surprisingly similar structure as spatial quantum correlations, formally related via the Choi-Jamiolkowski isomorphism. As a consequence, multi-time processes are endowed with the same richness as many-body physics, including temporal entanglement and well-defined causal structures. We […]

Quantum Computing – Qiskit Runtime

Qiskit Runtime is a quantum computing service and programming model that allows users to optimize workloads and efficiently execute them on quantum systems at scale. The programming model extends the existing interface in Qiskit with a set of new primitive programs. Jessie Yu, senior software engineer, explains Qiskit Runtime on a lightboard to get you […]
