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

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.

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

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

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.

Quantum computers, systems that process information leveraging quantum mechanical effects, could outperform classical computers on some computationally demanding tasks. Despite their potential, as the size of quantum computers increases,

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