Classical computations rely on binary bits, which can be in either of the two states, 0 or 1. In contrast, quantum computing is based on qubits, which can be 0, 1, or a superposition or entanglement ...

Researchers have developed a method to model a central theory of quantum gravity in the laboratory. Their goal: to decipher previously unexplained phenomena in the quantum world. Gravity is no longer ...

The quantum tangent kernel method is a mathematical approach used to understand how fast and how well quantum neural networks can learn. A quantum neural network is a machine learning model that runs ...

BUFFALO, N.Y. — Imagine zooming into matter at the quantum scale, where tiny particles can interact in more than a trillion configurations at once. If that sounds complicated, it is: Physicists often ...

While the concept of quantum computing has been discussed for more than 40 years, only recently have experiments indicated that a practical quantum computer may be possible. Recent developments in ...

Quantum physicists have found a way to make clouds of atomic-scale spins act like a single, disciplined antenna, generating microwave signals that are both powerful and remarkably long lived. Instead ...

Quantum spin liquids are fascinating states of matter where magnetic spins stay disordered, defying the usual rules of magnetism. Scientists have made an exciting discovery about one such material.

Quantum theory and Einstein's theory of general relativity are two of the greatest successes in modern physics. Each works ...

Last week I wrote about the current state of quantum sensing and quantum computing, including predictions on how soon quantum will be mature enough for practical applications. I recommend you read ...

Physicists have transformed a decades-old technique for simplifying quantum equations into a reusable, user-friendly "conversion table" that works on a laptop and returns results within hours. When ...
