Paper

Self-testing with finite statistics enabling the certification of a quantum network link

Jean-Daniel Bancal, Kai Redeker, Pavel Sekatski, Wenjamin Rosenfeld, and Nicolas Sangouard,

Quantum 5, 401 (2021).

Self-testing is a method to certify devices from the result of a Bell test. Although examples of noise tolerant self-testing are known, it is not clear how to deal efficiently with a finite…

Paper

Stabilizer extent is not multiplicative

Arne Heimendahl, Felipe Montealegre-Mora, Frank Vallentin, and David Gross,

Quantum 5, 400 (2021).

The Gottesman-Knill theorem states that a Clifford circuit acting on stabilizer states can be simulated efficiently on a classical computer. Recently, this result has been generalized to cov…

Paper

A quantum algorithm for the direct estimation of the steady state of open quantum systems

Nathan Ramusat and Vincenzo Savona,

Quantum 5, 399 (2021).

Simulating the dynamics and the non-equilibrium steady state of an open quantum system are hard computational tasks on conventional computers. For the simulation of the time evolution, sever…

Paper

Non-Pauli topological stabilizer codes from twisted quantum doubles

Julio Carlos Magdalena de la Fuente, Nicolas Tarantino, and Jens Eisert,

Quantum 5, 398 (2021).

It has long been known that long-ranged entangled topological phases can be exploited to protect quantum information against unwanted local errors. Indeed, conditions for intrinsic topologic…

Paper

Resource requirements for efficient quantum communication using all-photonic graph states generated from a few matter qubits

Paul Hilaire, Edwin Barnes, and Sophia E. Economou,

Quantum 5, 397 (2021).

Quantum communication technologies show great promise for applications ranging from the secure transmission of secret messages to distributed quantum computing. Due to fiber losses, long-dis…

Paper

Cost-optimal single-qubit gate synthesis in the Clifford hierarchy

Gary J. Mooney, Charles D. Hill, and Lloyd C. L. Hollenberg,

Quantum 5, 396 (2021).

For universal quantum computation, a major challenge to overcome for practical implementation is the large amount of resources required for fault-tolerant quantum information processing. An…

Paper

Rapid mixing of path integral Monte Carlo for 1D stoquastic Hamiltonians

Elizabeth Crosson and Aram W. Harrow,

Quantum 5, 395 (2021).

Path integral quantum Monte Carlo (PIMC) is a method for estimating thermal equilibrium properties of stoquastic quantum spin systems by sampling from a classical Gibbs distribution using Ma…

Paper

Exact and approximate continuous-variable gate decompositions

Timjan Kalajdzievski and Nicolás Quesada,

Quantum 5, 394 (2021).

We gather and examine in detail gate decomposition techniques for continuous-variable quantum computers and also introduce some new techniques which expand on these methods. Both exact and a…

Paper

A resource efficient approach for quantum and classical simulations of gauge theories in particle physics

Jan F. Haase, Luca Dellantonio, Alessio Celi, Danny Paulson, Angus Kan, Karl Jansen, and Christine A. Muschik,

Quantum 5, 393 (2021).

Gauge theories establish the standard model of particle physics, and lattice gauge theory (LGT) calculations employing Markov Chain Monte Carlo (MCMC) methods have been pivotal in our unders…

Paper

Blueprint for a Scalable Photonic Fault-Tolerant Quantum Computer

J. Eli Bourassa, Rafael N. Alexander, Michael Vasmer, Ashlesha Patil, Ilan Tzitrin, Takaya Matsuura, Daiqin Su, Ben Q. Baragiola, Saikat Guha, Guillaume Dauphinais, Krishna K. Sabapathy, Nicolas C. Menicucci, and Ish Dhand,

Quantum 5, 392 (2021).

Photonics is the platform of choice to build a modular, easy-to-network quantum computer operating at room temperature. However, no concrete architecture has been presented so far that explo…
