An American physicist and Canadian computer scientist received the A.M. Turing Award on Wednesday for their groundbreaking work on quantum key cryptography.

Australia’s quantum push is accelerating, with real systems, bold timelines, and breakthroughs like quantum twins signaling a shift in the global tech race.

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,

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.

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.

The world of quantum computing has its fair share of believers and sceptics. While some call it the technology of the future that could see many modern technologies like cryptography rendered useless,

The hope for quantum computers is that the devices will be able to solve complex tasks such as predicting how chemicals react or cracking encrypted text. One of the main reasons that the machines are not yet living up to that potential is the fact that their error rates are high.

Quantum computers promise to revolutionize whole industries by outperforming classical computers on complex calculations. They just need to be colder than the coldest natural place in the universe.

IBM and an international team of researchers have used a quantum computer to accurately simulate the electronic structure of a real molecule, a task that many scientists believed was still out of reach for current quantum hardware.

Studying and designing novel materials is a central application of quantum mechanics. Chemists, materials scientists, and physicists focus on subtle interactions in quantum materials and to uncover them they rely on sophisticated computational and experimental techniques.
