Quantum distance refers to a measure of quantum mechanical similarity between two quantum states. A quantum distance of one means that the two quantum states are the same, whereas a quantum distance ...

Quantum teleportation is a fascinating process that involves transferring a particle's quantum state to another distant location, without moving or detecting the particle itself. This process could be ...

Among numerous other developments, in March 2024, Quantinuum announced a breakthrough in the ability to build a large-scale quantum computer. A month later, at the Quantum World Congress, IBM, ...

While quantum entanglement mimicks the first law of thermodynamics in terms of entropy in a system, scientists wonder if the second law—especially the part about reversibility—could hold true. A new ...

Microsoft team led by UC Santa Barbara physicists unveils first-of-its-kind topological qubit, paving the way for a more fault-tolerant quantum computer In a leap forward for quantum computing, a ...

From where we're sitting today, it's increasingly likely that quantum computing will be one of the most disruptive technologies on the medium-term horizon. Here’s why: Harnessing the properties of ...

A team of CU Boulder researchers has introduced a quantum sensing technique that could lead to improvements in how we monitor infrastructure, detect changes in the environment and conduct geophysical ...

Tech giants, global governments, and infrastructure providers must work together to implement post-quantum cryptographic standards, ensure secure migration paths, and educate the leadership class ...

One day soon, at a research lab near Santa Barbara or Seattle or a secret facility in the Chinese mountains, it will begin: the sudden unlocking of the world’s secrets. Your secrets. Cybersecurity ...
