Quantum computers are expected to break modern public key cryptography owing to Shor's
algorithm. As a result, these cryptosystems need to be replaced by quantum-resistant …

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 …

Quantum cryptography exploits principles of quantum physics for the secure processing of
information. A prominent example is secure communication, ie, the task of transmitting …

We present a protocol which allows a client to have a server carry out a quantum
computation for her such that the client's inputs, outputs and computation remain perfectly …

Quantum cryptography is the art and science of exploiting quantum mechanical effects in
order to perform cryptographic tasks. While the most well-known example of this discipline is …

A thorough exposition of quantum computing and the underlying concepts of quantum
physics, with explanations of the relevant mathematics and numerous examples. The …

One formidable difficulty in quantum communication and computation is to protect
information-carrying quantum states against undesired interactions with the environment. To …

We present a quantum digital signature scheme whose security is based on fundamental
principles of quantum physics. It allows a sender (Alice) to sign a message in such a way …

Quantum computers promise to efficiently solve not only problems believed to be intractable
for classical computers, but also problems for which verifying the solution is also considered …

Blind quantum computing (BQC) allows a client to have a server carry out a quantum
computation for them such that the client's input, output, and computation remain private. A …
