TechnologyAnother quantum computer reached quantum advantage – does it matter? A quantum computer that uses particles of light took about two dozen microseconds to complete a calculation that may take trillions of trillions of trillions of years on the world’s best supercomputers 51¶¯Âþ
PhysicsCould we get quantum spookiness even without entanglement? Particles of light travelling through a maze of devices seem to have passed a famous test for entanglement – without being entangled at all 51¶¯Âþ
