Optimizing SWAP networks for quantum computing

 Quantum Physics News
 04 August 2022
A research partnership at the Advanced Quantum Testbed (AQT) at Lawrence Berkeley National Laboratory (Berkeley Lab) and Chicago-based Super.tech (acquired by ColdQuanta in May 2022) demonstrated how to optimize the execution of the ZZ SWAP network protocol, important to quantum computing. The team...

The strength of the strong force

Much ado was made about the Higgs boson when this elusive particle was discovered in 2012. Though it was touted as giving ordinary matter mass, interactions with the Higgs field only generate about 1 percent of ordinary mass. The other 99 percent comes from phenomena associated with the strong...

Developing a new approach for building quantum computers

Yet-to-be discovered axions and axion-like particles may be the key to explaining some of the deepest puzzles of our universe, such as dark matter and charge-parity violation in strong interactions. Several recent theories have predicted that the masses of axions probably lie within the...

New method of controlling qubits could advance quantum computers

 Quantum Physics News
 28 July 2022
Quantum computing, a field that relies on the principles of quantum mechanics to calculate outcomes, has the potential to perform tasks too complex for traditional computers and to do so at high speeds, making it in some ways the new frontier for science and engineering. To get to the point where...

A nanokelvin microwave freezer for molecules

When a highly diluted gas is cooled to extremely low temperatures, bizarre properties are revealed. Thus, some gases form a so-called Bose-Einstein condensate—a type of matter in which all atoms move in unison. Another example is supersolidity: a state in which matter behaves like a frictionless...
