Controlling qubits with quantum superpositions allows them to dramatically violate a fundamental limit and encode information ...

Three thought experiments involving “demons” have haunted physics for centuries. What should we make of them today?

Fundamental physics faces a stubborn paradox: the current impossibility of reconciling the rules of the quantum world with those of gravity, despite a century of efforts. This theoretical ...

Time travel is deterministic and locally free, a paper says —resolving an age-old paradox. This follows research observing ...

The exploration of quantum information challenges objective reality, positing the universe as a hologram is explored through ...

The constancy of the speed of light is a pillar of modern physics, but questions persist about its absolute universality.

On Nov. 29, 1947, the United Nations voted for the partition of Palestine and the creation of the independent Jewish state of ...

For as long as people have looked for answers in the night sky, the idea of stepping into a machine and arriving in an earlier moment in time has kept our imagination alive. But a new study offers a ...

The perplexity of quantum mechanics lies in the unpredictable behavior of its particles, making it a challenging field to ...

A new study from Oxford shows quantum clocks may not be as energy efficient as once thought, but only when we look at them.
