Researchers at IIT Bombay have proposed a new test, dynamical fidelity susceptibility (DFS), to measure the 'quantumness' of gravity, suggesting that conventional entanglement-based tests may be ...

Over the past decades, energy engineers have developed increasingly advanced battery technologies that can store more energy, charge faster and maintain their performance for longer. In recent years, ...

Abstract: Quantum key distribution (QKD) can provide secure key material between two parties without relying on assumptions about the computational power of an eavesdropper. QKD is performed over ...

A team of researchers has demonstrated a quantum-classical hybrid system that transmits quantum-secured data over ordinary ...

Scientists at TU Delft have designed a nanostring resonator that, when driven at its lowest vibration frequency, quietly funnels energy through a chain of higher modes all the way up to the fifth, ...

Cables underneath New York City are teeming with entangled quantum particles of light thanks to Qunnect, a company that has ...

One of the most picturesque and oldest campuses in the country became a living stage last weekend as the 200-year-old CMS College, Kottayam hosted a promenade theatre adaptation of N S Madhavan’s ...

A team in China has demonstrated the simultaneous teleportation of multiple sideband qumodes in a continuous-variable system, overcoming a longstanding technical barrier.

While the basic form of QKD enables information to be transmitted securely, it does have some weak points. One of them is ...

Quantum technologies, devices and systems that operate leveraging quantum mechanical effects, could tackle some tasks more reliably and efficiently than any classical technology could. In recent years ...
