Surface code quantum computing by lattice surgery
This paper introduces a new technique enabling the coupling of two planar codes without transversal operations, maintaining the 2DNN of the encoded computer, and shows how lattice surgery allows us to distribute encoded GHZ states in a more direct manner, and how a demonstration of an encoded CNOT between two distance-3 logical states is possible with 53 physical qubits.
Quantum error correction for beginners
The basic aspects of quantum error correction and fault-tolerance are examined largely through detailed examples, which are more relevant to experimentalists today and in the near future.
Implementation of Shor's algorithm on a linear nearest neighbour qubit array
A circuit implementing Shor's factorisation algorithm designed for such a linear nearest neighbour architecture with interaction restrictions, which is identical to leading order to that possible using an architecture that can interact arbitrary pairs of qubits.
A bridge to lower overhead quantum computation
This work addresses the second challenge of practical large-scale quantum computation, presenting a new technique, bridge compression, which enables remarkably low volume structures to be found that implement complex computations in the surface code.
Quantum communication without the necessity of quantum memories
Researchers propose a design of quantum communication based on directly transmitting quantum information in encoded form across a network that potentially provides higher communication rates than existing entanglement-based schemes.
Requirements for fault-tolerant factoring on an atom-optics quantum computer.
This work estimates the resources required to execute Shor's factoring algorithm on an atom-optics quantum computer architecture and suggests that once the physical error rate is low enough to allow quantum error correction, optimization to reduce resources and increase performance will come mostly from integrating algorithms and circuits within the error correction environment.
Surface code implementation of block code state distillation
It is found that, using the best available techniques, for parameters of practical interest, block code state distillation does not always lead to lower overhead, and, when it does, the overhead reduction is typically less than a factor of three.
Blueprint for a microwave trapped ion quantum computer
This work presents a blueprint for a trapped ion–based scalable quantum computer module, making it possible to create a scalable quantumComputer architecture based on long-wavelength radiation quantum gates.
The Path to Scalable Distributed Quantum Computing
Researchers are fabricating quantum processors powerful enough to execute small instances of quantum algorithms, and experimental efforts have demonstrated some of the building blocks for such a design.
