“This retroactive idea. It has to be that,” says Nobel Prize-winning mathematical physicist Sir Roger Penrose, reflecting on a problem about the building blocks of reality that has dogged physics for ...

In the Valis experiment, the quantum device is a single bit on an IBM Eagle chip, and the large device is the microwave control system that connects the qubits to the real world. These usually allow ...

The collapse of the quantum wave function – in which quantum objects go from existing within many possible states at once to settling into a concrete one understood by classical physics – does not ...

The twenty-first century has undoubtedly been the era of quantum science. Quantum mechanics was born in the early twentieth century and has been used to develop unprecedented technologies which ...
