The Thermodynamics of Quantum Computing

In research on quantum computers, one aspect that has been mostly neglected until now is the generation of heat....

Error Control Begins to Shape Quantum Architectures

Quantum computing has a crucial weakness that may severely delay, if not kill outright, its chances of becoming a way of running algorithms that classical computers cannot handle: its susceptibility...

A Sobering Reminder of Where We Currently Stand

[R]eluctance to accept that practical quantum computing has arrived presumably stems from the question of whether it can do anything truly useful yet. Sure, one can construct a problem that...

It’s Out! New Theory and Calculations to Predict Spin Decoherence in Materials With High Accuracy

Marco Bernardi, professor of applied physics, physics and materials science; and Jinsoo Park (MS '20, PhD '22), postdoctoral scholar research associate in applied physics and materials science, have developed a...

Crucial Leap in Error Mitigation for Quantum Computers

Researchers at Lawrence Berkeley National Laboratory’s Advanced Quantum Testbed (AQT) demonstrated that an experimental method known as randomized compiling (RC) can dramatically reduce error rates in quantum algorithms and lead...

Quantum Information Disappears at the Atomic Scale, Brookhaven and Princeton U Scientists Look to Find Sources of Loss

Engineers and materials scientists studying superconducting quantum information bits (qubits)—a leading quantum computing material platform based on the frictionless flow of paired electrons—have collected clues hinting at the microscopic sources of qubit information...
