New largest number factored on a quantum device is 56,153

(Phys.org)—Researchers have set a new record for the quantum factorization of the largest number to date, 56,153, smashing the previous record of 143 that was set in 2012. They have shown that the exact same room-temperature ...

Physicists reverse time using quantum computer

Researchers from the Moscow Institute of Physics and Technology teamed up with colleagues from the U.S. and Switzerland and returned the state of a quantum computer a fraction of a second into the past. They also calculated ...

Researchers 'teleport' a quantum gate

Yale University researchers have demonstrated one of the key steps in building the architecture for modular quantum computers: the "teleportation" of a quantum gate between two qubits, on demand.

Physicists record 'lifetime' of graphene qubits

Researchers from MIT and elsewhere have recorded, for the first time, the "temporal coherence" of a graphene qubit—meaning how long it can maintain a special state that allows it to represent two logical states simultaneously. ...

Engineers make critical advance in quantum computer design

Quantum engineers from UNSW Sydney have removed a major obstacle that has stood in the way of quantum computers becoming a reality. They discovered a new technique they say will be capable of controlling millions of spin ...

Is teleportation possible? Yes, in the quantum world

"Beam me up" is one of the most famous catchphrases from the Star Trek series. It is the command issued when a character wishes to teleport from a remote location back to the Starship Enterprise.
