The entangled clocks can test how quantum theory behaves in the presence of curved space-time as predicted by Einstein, or whether our current theories break down. Hoboken, N.J., July 14, 2025 — ...

Is the universe itself the ultimate editor of history, quietly erasing any contradictions before they can even take root? That’s the provocative implication of new research from Lorenzo Gavassino, a ...

Quantum mechanics and relativity are the two pillars of modern physics. However, for over a century, their treatment of space and time has remained fundamentally disconnected. Relativity unifies space ...

What does it mean to be to space-time? The seemingly simple question gets to the essence of twentieth-century physics and has driven a hundred-year debate between philosophy and science. In Einstein’s ...

Matrix models have emerged as a powerful framework in theoretical physics, offering a nonperturbative approach to describing quantum space-time. In these models, fundamental degrees of freedom are ...

Collaboration to demonstrate quantum networking and secure communications via Capella Space, expanding U.S. quantum space capabilities IonQ (NYSE: IONQ), the leader in the quantum computing and ...

Two blind spots torture physicists: the birth of the universe and the center of a black hole. The former may feel like a moment in time and the latter a point in space, but in both cases the normally ...

A number of experiments have been proposed to generate and witness gravitational entanglement, but Aziz and Howl’s work suggests that the presence of gravitational entanglement is not a ‘smoking gun’ ...

Hoboken, N.J., July 14, 2025 — Quantum networking is being rapidly developed world-wide. It is a key quantum technology that will enable a global quantum internet: the ability to deploy secure ...
