Physicists have engineered photons that behave as if they inhabit a space far richer than the familiar three dimensions, ...

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

Continuous-variable quantum cryptography has emerged as a significant branch of quantum cryptography, with continuous-variable quantum key distribution (CVQKD) at its core. However, compared to ...

The concept of quantum entanglement is emblematic of the gap between classical and quantum physics. Referring to a situation in which it is impossible to describe the physics of each photon separately ...

Reliably quantifying and characterizing the quantum states of various systems is highly advantageous for both quantum physics research and the development of quantum technologies. Quantifying these ...

Impressively, the unit registered the lowest frequency loss of any chip to date. Specifically, the engineers noted that the new chip was 15x more stable and 100x more efficient in terms of microwave ...

Scientists have finally unlocked a way to identify the elusive W state of quantum entanglement, solving a decades-old problem and opening paths to quantum teleportation and advanced quantum ...

Microsoft scientists have created a quantum processor that taps into a rare state of matter that was first theorized in the 1930s, paving the way for a processor with a million qubits within years.
