With quantum computers of significant size now on the horizon, we should understand how
to best exploit their initially limited abilities. To this end, we aim to identify a practical problem …

Quantum computers can execute algorithms that dramatically outperform classical
computation. As the best-known example, Shor discovered an efficient quantum algorithm …

Quantum computation represents a threat to many cryptographic protocols in operation
today. It has been estimated that by 2035, there will exist a quantum computer capable of …

CSIDH is a recent proposal for post-quantum non-interactive key-exchange, based on
supersingular elliptic curve isogenies. It is similar in design to a previous scheme by …

Cryptography is considered indispensable among security measures applied to data

We present a scalable star-shaped quantum-key-distribution (QKD) optical-fiber network.
We use wavelength-division demultiplexing (WDM) of broadband photon pairs to establish …

Quantum circuits of many qubits are extremely difficult to realize; thus, the number of qubits
is an important metric in a quantum circuit design. Further, scalable and reliable quantum …

An explicit quantum design of AES-128 is presented in this paper. The design is structured
to utilize the lowest number of qubits. First, the main components of AES-128 are designed …
