Quantum Supremacy Is Coming: Here’s What You Should Know
Researchers are getting close to building a quantum computer that can perform tasks a classical computer can’t. Here’s what the milestone will mean.
How to Turn a Quantum Computer Into the Ultimate Randomness Generator
Pure, verifiable randomness is hard to come by. Two proposals show how to make quantum computers into randomness factories.
A New Law to Describe Quantum Computing’s Rise?
Neven’s law states that quantum computers are improving at a “doubly exponential” rate. If it holds, quantum supremacy is around the corner.
Computer Scientists Expand the Frontier of Verifiable Knowledge
The universe of problems that a computer can check has grown. The researchers’ secret ingredient? Quantum entanglement.
A New Approach to Multiplication Opens the Door to Better Quantum Computers
Quantum computers can’t selectively forget information. A new algorithm for multiplication shows a way around that problem.
Quantum Machine Appears to Defy Universe’s Push for Disorder
One of the first quantum simulators has produced a puzzling phenomenon: a row of atoms that repeatedly pops back into place.
How Space and Time Could Be a Quantum Error-Correcting Code
The same codes needed to thwart errors in quantum computers may also give the fabric of space-time its intrinsic robustness.
Milestone Experiment Proves Quantum Communication Really Is Faster
In a Paris lab, researchers have shown for the first time that quantum methods of transmitting information are superior to classical ones.
Graduate Student Solves Quantum Verification Problem
Urmila Mahadev spent eight years in graduate school solving one of the most basic questions in quantum computation: How do you know whether a quantum computer has done anything quantum at all?
