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 […]

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 […]

Microwave Amplifiers for Quantum Information Processing with Florent Q. Lecocq

Speaker Florent Q. Lecocq explains the use of microwave amplifiers for QIP. Abstract: In the late 2000s, the application of low-noise parametric amplifiers to cryogenic microwave measurements revolutionized the field of quantum information processing with superconducting circuits. For example, it enabled high-fidelity dispersive qubit readout, a ubiquitous tool in current superconducting quantum computers. Importantly, it […]

How African Researchers Are Building a Quantum Community from the Ground Up

Here’s an interesting article from Qiskit on efforts to build a quantum computing community in Africa. “By 2050, the population of Africa will double,” said Barry Dwolatzky, emeritus professor of electrical and information engineering at the University of Witwatersrand (Wits University) in Johannesburg, South Africa. Current projections indicate that most of this growing population will […]

Where Do We Go Next with Quantum Computing?

QC40 was a one-day virtual event that celebrated the 40th anniversary of the Physics of Computation Conference, which was jointly organized by MIT and IBM and held in the Endicott House on the MIT campus in 1981. We consider this conference a defining moment in the history of quantum computation. At QC40, we looked at […]

Quantum Mechanics Isn’t Weird, We’re Just Too Big

In this talk, Phillip Ball explains why quantum mechanics is not weird. Quantum computers rely on concepts such as superposition and entanglement that defy our intuitions about how things can behave. It’s often said that the world is quantum-mechanical and weird at small scales, and classical and familiar at human scales. I will challenge that […]
