Demonstrating Quantum Error Correction that Extends the Lifetime of Quantum Information

N. Ofek, A. Petrenko, R. Heeres +10 more·Feb 15, 2016

The remarkable discovery of Quantum Error Correction (QEC), which can overcome the errors experienced by a bit of quantum information (qubit), was a critical advance that gives hope for eventually realizing practical quantum computers. In principle, ...

The role of master clock stability in scalable quantum information processing

H. Ball, W. Oliver, M. Biercuk·Feb 15, 2016

Experimentalists seeking to improve the coherent lifetimes of quantum bits have generally focused on mitigating decoherence mechanisms through, for example, improvements to qubit designs and materials, and system isolation from environmental perturba...

Correction of data and syndrome errors by stabilizer codes

A. Ashikhmin, C. Lai, T. Brun·Feb 4, 2016

Performing active quantum error correction to protect fragile quantum states highly depends on the correctness of error information-error syndromes. To obtain reliable error syndromes using imperfect physical circuits, we propose the idea of quantum ...

GaAs integrated quantum photonics: Towards compact and multi‐functional quantum photonic integrated circuits

C. Dietrich, A. Fiore, M. Thompson +2 more·Jan 26, 2016

The recent progress in integrated quantum optics has set the stage for the development of an integrated platform for quantum information processing with photons, with potential applications in quantum simulation. Among the different material platform...

Single-ion microwave near-field quantum sensor

M. Wahnschaffe, H. Hahn, G. Zarantonello +5 more·Jan 25, 2016

We develop an intuitive model of 2D microwave near-fields in the unusual regime of centimeter waves localized to tens of microns. Close to an intensity minimum, a simple effective description emerges with five parameters that characterize the strengt...

On-chip coherent conversion of photonic quantum entanglement between different degrees of freedom

Lantian Feng, Ming Zhang, Zhi-yuan Zhou +8 more·Jan 23, 2016

In the quantum world, a single particle can have various degrees of freedom to encode quantum information. Controlling multiple degrees of freedom simultaneously is necessary to describe a particle fully and, therefore, to use it more efficiently. He...

Spontaneous emission of Schrödinger cats in a waveguide at ultrastrong coupling

Nicolas Gheeraert, S. Bera, S. Florens·Jan 7, 2016

Josephson circuits provide a realistic physical setup where the light–matter fine structure constant can become of order one, allowing to reach a regime dominated by non-perturbative effects beyond standard quantum optics. Simple processes, such as s...

Black hole based quantum computing in labs and in the sky

G. Dvali, M. Panchenko·Jan 6, 2016

Analyzing some well established facts, we give a model‐independent parameterization of black hole quantum computing in terms of a set of macro and micro quantities and their relations. These include the relations between the extraordinarily‐small ene...

A Study on Fast Gates for Large-Scale Quantum Simulation with Trapped Ions

R. Taylor, C. Bentley, J. S. Pedernales +4 more·Jan 4, 2016

Large-scale digital quantum simulations require thousands of fundamental entangling gates to construct the simulated dynamics. Despite success in a variety of small-scale simulations, quantum information processing platforms have hitherto failed to d...

Quantum interference between transverse spatial waveguide modes

A. Mohanty, Mian Zhang, A. Dutt +3 more·Jan 1, 2016

Integrated quantum optics has the potential to markedly reduce the footprint and resource requirements of quantum information processing systems, but its practical implementation demands broader utilization of the available degrees of freedom within ...

Reversing quantum dynamics with near-optimal quantum and classical fidelity

H. Barnum, E. Knill·Apr 23, 2000

We consider the problem of reversing quantum dynamics, with the goal of preserving an initial state's quantum entanglement or classical correlation with a reference system. We exhibit an approximate reversal operation, adapted to the initial density ...
