Conditions for superdecoherence

Joris Kattemölle, Jasper van Wezel

Decoherence is the main obstacle to quantum computation. The decoherence rate per qubit is typically assumed to be constant. It is known, however, that quantum registers coupling t…

Weak approximate unitary designs and applications to quantum encryption

Cécilia Lancien, Christian Majenz

Unitary -designs are the bread and butter of quantum information theory and beyond. An important issue in practice is that of efficiently constructing good approximations of suc…

Quantum Gravity in the Lab: Teleportation by Size and Traversable Wormholes

Adam R. Brown, Hrant Gharibyan, Stefan Leichenauer +6

With the long-term goal of studying models of quantum gravity in the lab, we propose holographic teleportation protocols that can be readily executed in table-top experiments. Thes…

Efficient simulation of random states and random unitaries

Gorjan Alagic, Christian Majenz, Alexander Russell

We consider the problem of efficiently simulating random quantum states and random unitary operators, in a manner which is convincing to unbounded adversaries with black-box oracle…

Single-step implementation of high fidelity -bit Toffoli gate

S. E. Rasmussen, K. Groenland, R. Gerritsma +2

The family of -bit Toffoli gates, with the two-bit Toffoli gate as the figurehead, are of great interest in quantum information as they can be used as universal gates and in qua…

Secure Multi-party Quantum Computation with a Dishonest Majority

Yfke Dulek, Alex B. Grilo, Stacey Jeffery +2

The cryptographic task of secure multi-party (classical) computation has received a lot of attention in the last decades. Even in the extreme case where a computation is performed…
