Transversality and lattice surgery: Exploring realistic routes toward coupled logical qubits with trapped-ion quantum processors
Mauricio Gutiérrez, Mauricio Gutiérrez, Markus Müller +3 more·Jan 22, 2018
Active quantum error correction has been identified as a crucial ingredient of future quantum computers, motivating the recent experimental efforts to encode logical quantum bits using small topological codes. In addition to the demonstration of the ...
Cooling by heating in nonequilibrium nanosystems
R. Hartle, C. Schinabeck, M. Kulkarni +3 more·Jan 22, 2018
We demonstrate the possiblity to cool nanoelectronic systems in nonequilibrium situations by increasing the temperature of the environment. Such cooling by heating is possible for a variety of experimental conditions where the relevant transport-indu...
Solid-state qubits
M. Gonzalez-Zalba·Jan 20, 2018
The quantum world is fascinating. It presents a description of nature that defies our most rooted concepts about what reality is. For example, quantum objects possess \lq\lq spooky\rq\rq\ properties that allow them to be in multiple places at the sam...
Demonstration of Topological Data Analysis on a Quantum Processor
Heliang Huang, Xi-Lin Wang, P. Rohde +7 more·Jan 19, 2018
Topological data analysis offers a robust way to extract useful information from noisy, unstructured data by identifying its underlying structure. Recently, an efficient quantum algorithm was proposed [Lloyd, Garnerone, Zanardi, Nat. Commun. 7, 10138...
Pair-cat codes: autonomous error-correction with low-order nonlinearity
Victor V. Albert, S. Mundhada, A. Grimm +3 more·Jan 18, 2018
We introduce a driven-dissipative two-mode bosonic system whose reservoir causes simultaneous loss of two photons in each mode and whose steady states are superpositions of pair-coherent/Barut-Girardello coherent states. We show how quantum informati...
Exact quantum query complexity of weight decision problems via Chebyshev polynomials
Xiaoyu He, Xiaoming Sun, Guang Yang +1 more·Jan 17, 2018
The weight decision problem, which requires to determine the Hamming weight of a given binary string, is a natural and important problem, with applications in cryptanalysis, coding theory, fault-tolerant circuit design and so on. In particular, both ...
Deterministic teleportation of a quantum gate between two logical qubits
K. Chou, J. Blumoff, J. Blumoff +8 more·Jan 16, 2018
A quantum computer has the potential to efficiently solve problems that are intractable for classical computers. However, constructing a large-scale quantum processor is challenging because of the errors and noise that are inherent in real-world quan...
Quantum Schur Sampling Circuits can be Strongly Simulated.
Vojtěch Havlíček, Sergii Strelchuk·Jan 15, 2018
Permutational quantum computing (PQC) [Quantum Inf. Comput., 10, 470-497 (2010)QICUAW1533-7146] is a natural quantum computational model conjectured to capture nonclassical aspects of quantum computation. An argument backing this conjecture was the o...
General framework for constructing fast and near-optimal machine-learning-based decoder of the topological stabilizer codes
Amarsanaa Davaasuren, Yasunari Suzuki, K. Fujii +1 more·Jan 13, 2018
Quantum error correction is an essential technique for constructing a scalable quantum computer. In order to implement quantum error correction with near-term quantum devices, a fast and near-optimal decoding method is demanded. A decoder based on ma...

One of the leading quantum computing architectures is based on the two-dimensional (2D) surface code. This code has many advantageous properties such as a high error threshold and a planar layout of physical qubits where each physical qubit need only...

We expand the time reversal symmetry arguments of quantum mechanics, originally proposed by Wigner in the context of unitary dynamics, to contain situations including generalized measurements for monitored quantum systems. We propose a scheme to deri...

Yuanhao Wang, Ying Li, Z. Yin +1 more·Jan 11, 2018
Entanglement is an important evidence that a quantum device can potentially solve problems intractable for classical computers. In this paper, we prepare connected graph states involving 8 to 16 qubits on ibmqx5, a 16-qubit superconducting quantum pr...

We report a quantum simulation of the deuteron binding energy on quantum processors accessed via cloud servers. We use a Hamiltonian from pionless effective field theory at leading order. We design a low-depth version of the unitary coupled-cluster a...
Quantum Algorithm for Simulating Real Time Evolution of Lattice Hamiltonians
Jeongwan Haah, M. Hastings, Robin Kothari +1 more·Jan 11, 2018
We study the problem of simulating the time evolution of a lattice Hamiltonian, where the qubits are laid out on a lattice and the Hamiltonian only includes geometrically local interactions (i.e., a qubit may only interact with qubits in its vicinity...
Construction and Performance of Quantum Burst Error Correction Codes for Correlated Errors
Jihao Fan, Min-Hsiu Hsieh, H. Chen +2 more·Jan 11, 2018
In practical communication and computation systems, errors occur predominantly in adjacent positions rather than in a random manner. In this paper, we develop a stabilizer formalism for quantum burst error correction codes (QBECC) to combat such erro...
