A century-old thought experiment on wave–particle duality is brought into the laboratory using a single trapped atom ...

To reach this conclusion, the researchers examined the most basic form of entanglement between identical particles using the concept of nonlocality introduced by physicist John Bell. While ...

While the idea of a quantum internet has a huge amount of potential, getting it hooked up to the regular old internet has its challenges. Now a new study hints at how existing and future networks ...

Quantum computing has long been constrained by the messy reality of controlling fragile qubits with bulky, power-hungry ...

Experiments reveal that metallic nanoparticles thousands of atoms wide can exist in quantum superposition, providing a ...

The 5.4 km free-space quantum communication link between the University of Ottawa and the National Research Council Canada, where real-time atmospheric turbulence measurements were conducted to train ...

The fields of Quantum Optics and Nonlinear Photonics merge quantum mechanics with advanced photonic engineering to explore and manipulate light at its most fundamental level. This interdisciplinary ...

A team of researchers has found one of the missing pieces of the hardware puzzle that allows quantum computers to function at ...

Quantum optics investigates the behaviour of light and its interactions with matter at the quantum level, revealing phenomena that are absent in classical descriptions. This field encompasses studies ...

There is a glaring gap in our knowledge of the physical world: none of our well-established theories describe gravity’s quantum nature. Yet physicists expect that this quantum nature is essential for ...

The original version of this story appeared in Quanta Magazine. Imagine standing on a railway platform watching a trolley go past. A girl on the trolley drops a bright red ball. To her, the ball falls ...
