Particles of light can spend "negative time" passing through a cloud of extremely cold atoms – without breaking the laws of physics

If gravity is a truly quantum entity, something as simple as measuring the strength of an object’s gravitational field should change its quantum state

A mathematical proof shows that some quantum states can resist nature’s tendency to disorder – but only under very specific conditions

A new technique uses glowing molecules, laser light and microscopes to measure distances as minuscule as 0.1 nanometres – the width of a typical atom

A mathematical study finds that three definitions of what it means for entropy to increase, which have previously been considered equivalent, can produce different results in the quantum realm

Researchers used a collection of charged atoms to create a quantum superposition of an exotic type of defect

A typically fragile quantum superposition has been made to last exceptionally long, and could eventually be used as a probe for discovering new physics

Simulations suggest that when a quantum battery shares a quantum state with the device it is powering, the device can gain more charge than was stored in the battery to begin with

Light can be directed and steered around bends using a method similar to the way clouds scatter photons, which could lead to advances in medical imaging, cooling systems and even nuclear reactors

Alan Turing's theories about computation seem to have a startling consequence, placing hard limits on how fast or slow any physical process in the universe can grow

A surprising reversal of our usual understanding of the second law of thermodynamics shows that it may be possible for heat to move in the “wrong” direction, flowing from a cold area to a warm one

Shapes created by vortices in water often fall apart, but an odd quantum fluid made from ultracold atoms could support vortex knots that never lose their knottiness

Allowing for moves that create quantum superpositions makes a quantum version of a Rubik’s cube incredibly complex, but not impossible to solve
