Thermal Entanglement, Specific Heat and Quantum Discord in Open Quantum Systems Including Non-Markovian Processes
B. Lari, H. Hassanabadi·Apr 10, 2017
Entanglement (EN) is a determinative correlation in designation of quantum gates and quantum memories. All quantum operations which are assembled by quantum circuits, are exposed to environment. However, quantum discord (QD) as a new key of resource ...
Quantum advantage with shallow circuits
S. Bravyi, David Gosset, R. König·Apr 3, 2017
Quantum outperforms classical Quantum computers are expected to be better at solving certain computational problems than classical computers. This expectation is based on (well-founded) conjectures in computational complexity theory, but rigorous com...
Information Theoretically Secure Hypothesis Test for Temporally Unstructured Quantum Computation (Extended Abstract)
Daniel Mills, Anna Pappa, Theodoros Kapourniotis +1 more·Apr 1, 2017
The efficient certification of classically intractable quantum devices has been a central research question for some time. However, to observe a "quantum advantage", it is believed that one does not need to build a large scale universal quantum compu...
Implementation of a quantum controlled-SWAP gate with photonic circuits
T. Ono, R. Okamoto, Masato Tanida +2 more·Mar 31, 2017
Quantum information science addresses how the processing and transmission of information are affected by uniquely quantum mechanical phenomena. Combination of two-qubit gates has been used to realize quantum circuits, however, scalability is becoming...
Experimental realization of single-shot nonadiabatic holonomic gates in nuclear spins
Hang Li, Yang Liu, Guilu Long·Mar 30, 2017
Nonadiabatic holonomic quantum computation has received increasing attention due to its robustness against control errors. However, all the previous schemes have to use at least two sequentially implemented gates to realize a general one-qubit gate. ...
Routes Towards Optical Quantum Technology --- New Architectures and Applications
Keith R. Motes·Mar 15, 2017
This thesis is based upon the work I have done during my PhD candidature at Macquarie University. In this work we develop quantum technologies that are directed towards realising a quantum computer. Specifically, we have made many theoretical advance...
Density-matrix simulation of small surface codes under current and projected experimental noise
T. O’Brien, B. Tarasinski, B. Tarasinski +1 more·Mar 12, 2017
We present a density-matrix simulation of the quantum memory and computing performance of the distance-3 logical qubit Surface-17, following a recently proposed quantum circuit and using experimental error parameters for transmon qubits in a planar c...
Heat-bath algorithmic cooling with correlated qubit-environment interactions
Nayeli A. Rodríguez-Briones, Jun Yu Li, Xinhua Peng +3 more·Mar 8, 2017
Cooling techniques are essential to understand fundamental thermodynamic questions of the low-energy states of physical systems, furthermore they are at the core of practical applications of quantum information science. In quantum computing, this con...
Polarization-entangled photon pair sources based on spontaneous four wave mixing assisted by polarization mode dispersion
Pisek Kultavewuti, E. Zhu, Xingxing Xing +4 more·Mar 7, 2017
Photonic-based qubits and integrated photonic circuits have enabled demonstrations of quantum information processing (QIP) that promises to transform the way in which we compute and communicate. To that end, sources of polarization-entangled photon p...
Faithful conversion of propagating quantum information to mechanical motion
A. Reed, A. Reed, K. Mayer +15 more·Mar 7, 2017
Combining micrometre-sized mechanical resonators with superconducting quantum circuits, quantum information encoded with photons now can be converted to the motion of a macroscopic object. The motion of micrometre-sized mechanical resonators can now ...

In this paper we propose a scheme to model the phonon analog of optical elements, including a polarizing beam splitter, a half- wave plate, and a quarter- wave plate, as well as an implementation of CNOT and Pauli gates, by using two atoms confined i...
Quantum Information Set Decoding Algorithms
Ghazal Kachigar, J. Tillich·Mar 1, 2017
The security of code-based cryptosystems such as the McEliece cryptosystem relies primarily on the difficulty of decoding random linear codes. The best decoding algorithms are all improvements of an old algorithm due to Prange: they are known under t...
