Unitary -designs from seeds
Rawad Mezher, Joe Ghalbouni, Joseph Dgheim +1
The capacity to randomly pick a unitary across the whole unitary group is a powerful tool across physics and quantum information. A unitary -design is designed to tackle this ch…
Non-interactive classical verification of quantum computation
Gorjan Alagic, Andrew M. Childs, Alex B. Grilo +1
In a recent breakthrough, Mahadev constructed an interactive protocol that enables a purely classical party to delegate any quantum computation to an untrusted quantum prover. In t…
QMA-hardness of Consistency of Local Density Matrices with Applications to Quantum Zero-Knowledge
Anne Broadbent, Alex B. Grilo
We provide several advances to the understanding of the class of Quantum Merlin-Arthur proof systems (QMA), the quantum analogue of NP. Our central contribution is proving a longst…
Authenticated teleportation and verification in a noisy network
Anupama Unnikrishnan, Damian Markham
Authenticated teleportation aims to certify the transmission of a quantum state through teleportation, even in the presence of an adversary. This scenario can be pictured in terms…
Quantum certification and benchmarking
J. Eisert, D. Hangleiter, N. Walk +5
Concomitant with the rapid development of quantum technologies, challenging demands arise concerning the certification and characterization of devices. The promises of the field ca…
Randomized Benchmarking in the Analogue Setting
Ellen Derbyshire, Jorge Yago Malo, Andrew Daley +2
Current development in programmable analogue quantum simulators (AQS), whose physical implementation can be realised in the near-term compared to those of large-scale digital quant…
