Quantum cryptography is arguably the fastest growing area in quantum information science.
Novel theoretical protocols are designed on a regular basis, security proofs are constantly …

The science of quantum information has arisen over the last two decades centered on the
manipulation of individual quanta of information, known as quantum bits or qubits. Quantum …

Abstract “Device-independent” not only represents a relaxation of the security assumptions
about the internal working of the quantum devices, but also can enhance the security of the …

The advanced notebooks, mobile phones, and Internet applications in today's world that we
use are all entrenched in classical communication bits of zeros and ones. Classical Internet …

Electrically driven semiconductor lasers are used in technologies ranging from
telecommunications and information storage to medical diagnostics and therapeutics. The …

Quantum continuous variables are being explored,,,,,,,,,,,, as an alternative means to
implement quantum key distribution, which is usually based on single photon counting. The …

We investigate the resources needed for secure teleportation of coherent states. We extend
continuous variable teleportation to include quantum teleamplification protocols that allow …

The recent launch of the Micius quantum-enabled satellite heralds a major step forward for
long-range quantum communication. Using single-photon discrete-variable quantum states …

We describe the observation of a “degaussification” protocol that maps individual pulses of
squeezed light onto non-Gaussian states. This effect is obtained by sending a small fraction …

Shor and Preskill (see Phys. Rev. Lett., vol. 85, p. 441, 2000) have provided a simple proof
of security of the standard quantum key distribution scheme by Bennett and Brassard (1984) …
