Engineering three-body interaction and Pfaffian states in circuit QED systems

August 18, 2014
Author(s)
Mohammad Hafezi, Prabin Adhikari, Jacob M. Taylor
We demonstrate a scheme to engineer the three-body interaction in circuit-QED systems by tuning a fluxonium qubit. Connecting such qubits in a square lattice and controlling the tunneling dynamics, in the form of a synthesized magnetic field, for the

Photon Emission from a Cavity-Coupled Double Quantum Dot

July 16, 2014
Author(s)
Y.-Y. Liu, Karl Petersson, J. Stehlik, Jacob Taylor, Jason Petta
We study a voltage biased InAs double quantum dot (DQD) that is coupled to a superconducting transmission line resonator. Inelastic tunneling in the DQD is mediated by electron phonon coupling and coupling to the cavity mode. We show that electronic

Trapping atoms using nanoscale quantum vacuum forces

July 10, 2014
Author(s)
Jacob M. Taylor, Darrick E. Chang, Kanupriya Sinha, H J. Kimble
Quantum vacuum forces dictate the interaction between individual atoms and dielectric surfaces at nanoscale distances. For example, their large strengths typically overwhelm externally applied forces, which makes it challenging to controllably interface

A classical channel model for gravitational decoherence

June 26, 2014
Author(s)
Jacob M. Taylor, Dvir Kafri, G J. Milburn
We show that, by treating the gravitational interaction between two mechanical resonators as a classical measurement channel, a gravitational decoherence model results that is equivalent to a model first proposed by Diosi. The resulting decoherence model

High Sensitivity Optomechanical Reference Accelerometer Over 10 kHz

June 5, 2014
Author(s)
Felipe Guzman, Lee M. Kumanchik, Jon R. Pratt, Jacob M. Taylor
We present an optically detected mechanical accelerometer that achieves a sensitivity of 100 ng/√Hz over a bandwidth of 10 kHz and is traceable. We have incorporated a Fabry-Perot fiber-optic micro-cavity that is currently capable of measuring the test

A single photon transistor based on superconducting systems

May 12, 2014
Author(s)
Marco Manzoni, Florentin Reiter, Jacob Taylor, Anders Sorensen
In analogy with electronic transistors, a single photon transistor is a device where the presence or absence of a single gate photon controls the propagation of a large number of signal photons [1, 2]. Such devices would represent a milestone in our

Topological physics with light

May 1, 2014
Author(s)
Jacob M. Taylor, Mohammad Hafezi
Electrons in a so-called topological insulator circulate around the material’s boundary without ever straying into the bulk. Uncharged photons can be induced to carry out similar behavior.

Optical detection of radio waves through a nanomechanical transducer

March 5, 2014
Author(s)
Jacob M. Taylor, Tolga Bagci, A Simonsen, Silvan Schmid, L Villanueva, Emil Zeuthen, Anders Sorensen, Koji Usami, A Schliesser, E.S. Polzik
Low-loss transmission and sensitive recovery of weak radio-frequency (rf) and mi- crowave signals is an ubiquitous technological challenge, crucial in fields as diverse as radio astronomy, medical imaging, navigation and communication, including those of

Graphene-on-dielectric micromembrane for optoelectromechanical hybrid devices

February 7, 2014
Author(s)
Jacob M. Taylor, Silvan Schmid, Tolga Bagci, Emil Zeuthen, Patrick Herring, Maja Cassidy, C. M. Marcus, Bartolo Amato, Anja Boisen, Yong C. Shin, Jing Kong, Anders Sorensen, Koji Usami, E.S. Polzik
Due to their exceptional mechanical and optical properties, dielectric silicon nitride (SiN) mi- cromembranes have become the centerpiece of many optomechanical experiments. Efficient capac- itive coupling of the membrane to an electrical system would

Ultra-Sensitive Chip-Based Photonic Temperature Sensor Using Ring Resonator Structures

February 3, 2014
Author(s)
Haitan Xu, Mohammad Hafezi, Jingyun Fan, Jacob Taylor, Gregory F. Strouse, Zeeshan Ahmed
Temperature is one of the most measured quantity in the world, second only to time. Recently there has been considerable interest in developing photonic temperature sensors to leverage advancements in frequency metrology. Here we show that Silicon based

Imaging topological edge states in silicon photonics

October 20, 2013
Author(s)
Mohammad Hafezi, Jingyun Fan, Alan L. Migdall, Jacob M. Taylor
Systems with topological oder exhibit exotic phenomena including fractional statistics. While most systems with topological order have been electronic, advances in our understanding of synthetic gauge fields have enabled realization of topological order in

State and Measurement Tomography of an Exchange-Only Spin Qubit

September 1, 2013
Author(s)
Jacob M. Taylor, Medford Jim, Johannes Beil, Stephen Bartlett, Andrew Doherty, Emmanuel Rashba, David P. DiVincenzo, H Lu, A. C. Gossard
We demonstrate the initialization, full electrical control, and state tomography of an exchange- only spin qubit in a GaAs heterostructure. Decoherence and leakage from the qubit subspace are accounted for with a model of charge noise and fluctuating

Electrically-protected resonant exchange qubits in triple quantum dots

July 31, 2013
Author(s)
Jacob M. Taylor, Vanita Srinivasa, Medford Jim
We present a modulated microwave approach for quantum computing with qubits comprising three spins in a triple quantum dot. This approach includes single- and two-qubit gates that are protected against low-frequency electrical noise, due to an operating
