Strongly interacting systems play an important role in quantum physics and quantum chemistry. Stochastic methods such as Monte Carlo simulations are a proven method for investigating such systems.

Their work introduces a new concept called q-desics, short for quantum-corrected paths through space–time. These paths ...

Governments and tech companies continue to pour money into quantum technology in the hopes of building a supercomputer that can work at speeds we can't yet fathom to solve big problems.

For more than a century, gravity has been the stubborn outlier in physics, resisting every attempt to merge Einstein’s smooth ...

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.

The race to harness quantum mechanics for computing power is finally colliding with the real economy. After a century of ...

Second, large-scale investment is arriving through national quantum-secure communication initiatives, from Europe’s EuroQCI ...

For decades, physicists taught that superconductivity and magnetism could not share the same space. One state should destroy ...
