Quantum Computer Makes Random-Number Breakthrough
Quantum Randomness Could Create a Spoof-Proof Internet Quantinuum’s 56-bit trapped-ion computer has succeeded in demonstrating randomness in quantum circuits to establish secure, private connections By Gayoung Lee & Lee Billings Quantinuum’s vacuum chamber. The allure of quantum computers is, at its heart, quite simple: by leveraging counterintuitive quantum effects, they could perform computational feats utterly…
Breakthrough Prize Winner Gerard ’t Hooft Says Quantum Mechanics Is ‘Nonsense’
Quantum Physics Is on the Wrong Track, Says Breakthrough Prize Winner Gerard ’t Hooft After netting the world’s highest-paying science award, preeminent theoretical physicist Gerard ’t Hooft reflects on his legacy and the future of physics By Lee Billings Gerard ’t Hooft. In the pantheon of modern physics, few figures can match the quiet authority…
Are D-Wave’s Claims of ‘Quantum Advantage’ Just ‘Quantum Hype’?
For Quantum Computing, Pressing the Advantage Is a Risky Proposition D-Wave’s fresh claim that it has achieved “quantum advantage” has sparked criticism of the company—and of the scientific process itself By Lee Billings edited by Dean Visser In a paper published in Science, an international team of more than 60 people led by D-Wave scientist…
Does Time Work Differently in the Quantum Realm?
In the Quantum Realm, Time’s Arrow Might Fly in Two Directions Scientists studying a centuries-old mystery of physics suggest two “arrows of time” control the evolution of quantum systems By Gayoung Lee edited by Lee Billings If a cup of water spills on the floor, the water can’t unspill—that is, it’s inconceivable that each water…
