PhysicsGiant atoms 'trapped' for record time at room temperature Putting unusually large atoms in a box with cold copper sides helped researchers control them for an unprecedented 50 minutes at room-temperature, an improvement necessary for building more powerful quantum computers and simulators ¿ìè¶ÌÊÓÆµ
TechnologyBreaking encryption with a quantum computer just got 20 times easier A quantum computer with a million qubits would be able to crack the vital RSA encryption algorithm, and while such machines don't yet exist, that estimate could still fall further ¿ìè¶ÌÊÓÆµ
