A vexing problem has long confronted quantum computer designers: the need to keep bits in a superconducting quantum processor free of errors and ready to perform calculations whenever necessary. These ...

A new leap in quantum technology is changing how scientists keep qubits—quantum computing’s building blocks—ready for work. Researchers have created a tiny refrigerator that can cool qubits to lower ...

The new quantum refrigerator, seen here in an artist's conception, is based on superconducting circuits. The device, which cools qubits to record low temperatures, is composed of two qubits---one hot ...

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

Researchers at Google have used their Willow quantum computer to demonstrate that "quantum contextuality" may be a crucial ...

Researchers created scalable quantum circuits capable of simulating fundamental nuclear physics on more than 100 qubits. These circuits efficiently prepare complex initial states that classical ...

A new physics paper takes a step toward creating a long-sought "theory of everything" by uniting gravity with the quantum world. However, the new theory remains far from being proven observationally.

A rift runs deep through the heart of physics. The general theory of relativity, which describes gravity, clashes with quantum physics. In an effort to seal that physics fissure, untold numbers of ...

What if the flow of time isn’t as one-way as it seems? Researchers from the University of Surrey have uncovered evidence that in the strange world of quantum physics, time could theoretically run both ...

Physicist Paul Davies’s Quantum 2.0: The past, present and future of quantum physics ends on a beautiful note. “To be aware of the quantum world is to glimpse something of the majesty and elegance of ...
