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.

They went on to show this approach could allow a quantum computer to break 256-bit elliptic curve cryptography (ECC) in 10 days while using 100 times less overhead than previously estimated. In a second paper,

Quantum computers are developing more quickly than expected – and so is the threat to our current computer security

The startup’s central idea to bring quantum computing to room temperature is even more outlandish than quantum itself: diamonds. The core idea of Quantum Brill

Quantum walks sound abstract, but they sit at the center of a very concrete race: who will harness quantum mechanics to solve problems that overwhelm today’s most powerful supercomputers. Instead of bits stepping randomly through data, quantum walkers ...

What once took up the entire space of IBM’s early computer lab now fits on a chip. The question is how and when will the world develop quantum on a chip.

Still confused about quantum investing? A fund like the Defiance Quantum ETF (QTUM) can make it easier to get started. At its core, QTUM is an exchange-traded fund that gives investors access to companies tied to next-gen tech.

A small mathematical revision to quantum mechanics could effectively limit the purported infinite capacities of quantum computers—if validated, that is.

Quantum processors operate in environments engineered to eliminate nearly all external interference. That just might make them perfect dark matter detectors.

HP and Dell announced new security capabilities to strengthen hardware-level protections against physical attacks and quantum threats.
