Einstein’s claim that the speed of light is constant has survived more than a century of scrutiny—but scientists are still ...

A new chip-based quantum memory uses 3D-printed “light cages” to store light in atomic vapor with high precision. Quantum ...

Take, for instance, quantum entanglement, which says that the state of one particle can be determined by examining the state ...

Scientists are learning to engineer light in rich, multidimensional ways that dramatically increase how much information a ...

University of Illinois Physics Professor Paul Kwiat and members of his research group have developed a new tool for precision measurement at the nanometer scale in scenarios where background noise and ...

For quantum computers to outperform their classical counterparts, they need more quantum bits, or qubits. State-of-the-art ...

A team of quantum physicists has taken a concept that once lived purely in equations and turned it into hardware reality, ...

EU researchers have brought supersolid light to life in the lab and are now exploring how this strange new state of matter could power real-world technologies. Can light ever be a solid? It turns out ...

Quantum phase transitions (QPTs) represent fundamental shifts in the ground state properties of a system driven by quantum fluctuations rather than thermal effects. The quantum Rabi model, which ...
