Charles H. Bennett and Gilles Brassard, winners of this year’s Turing Award, spent their lives touting the advantages of the quantum world

A team of physicists set out to test some of the most exciting claims in quantum computing—and found a very different story. Instead of confirming breakthroughs, their careful replication studies revealed that signals once hailed as major advances could actually be explained in simpler ways.

Light moving through a tiny silicon structure does not look dramatic. It slips down narrow waveguides etched onto a chip, guided by geometry too small to see with the naked eye.

Silicon is ubiquitous in modern electronics, and now it is becoming increasingly useful in quantum computing. In particular, silicon's compatibility with existing chip technology and its long coherence times in silicon-based spin qubits make it a promising material for scalable quantum computing.

Researchers at the University of Central Florida have demonstrated a method for generating scalable quantum entanglement on silicon photonic chips, a development that could help solve one of quantum computing’s most persistent problems: keeping entangled particles stable enough to be useful.

After the government's pledge to invest £2bn into quantum computing, how is the industry feeling?

Cisco signed a deal with Atom Computing to research the use of quantum networks to link neutral-atom quantum computers in support of distributed computing models, continuing Cisco’s ongoing work in quantum networking.
