A "Quantum Leap" Demonstration of Topological Quantum Computing

  • 22 February 2017

In May of 2016, the Director of NSF unveiled Big Ideas, developed to answer important societal problems while building the transdisciplinary portfolio of focused fundamental research over the next decade. One of these ideas, "Quantum Leap", advances quantum technologies of the future: quantum communication, quantum computing, quantum sensors and quantum simulators. The powerful language provided by quantum mechanics almost a century ago becomes the foundation upon which to build new industries. This process, sometimes called "the second quantum revolution" is marked by the development of practical and marketable solutions for quantum technologies. This Dear Colleague Letter (DCL) is intended to challenge the fundamental research community to achieve the transformative experimental realization of topological quantum computing.

Applications of Adiabatic Quantum Computation in Mathematical Optimization

Speaker(s): 
Pooya Ronagh
Dates: 
Friday, October 28, 2016 - 1:30pm to 3:00pm

Adiabatic quantum computation (AQC) is one of the paradigms of quantum computation that has recently gained great attention by advancements in manufacturing superconducting qubits. In this talk, I will overview the advantages and limitations of quantum annealers and methods of simulation of the behavior of futuristic devices. I will then discuss applicability of AQC in solving integer programming problems using a branch and bound framework implemented on a hybrid of a digital and a quantum processor.

The Information Directorate, High Performance Systems Branch, of the Air Force Research Laboratory (AFRL), Rome Research Site, is soliciting white papers under this announcement for innovative technologies to explore and develop computational capabilities with greater sophistication, autonomy, intelligence, and assurance for addressing dynamic mission requirements imposed by Command, Control, Communications, Computers, Intelligence, Surveillance and Reconnaissance (C4ISR) applications and Size Weight and Power (SWAP) constrained Air Force platforms.

Quantum Information Processing with 4 Electrons and 10^6 Nuclei

Tuesday, November 15, 2016 - 1:00pm to 2:00pm

Individual spins in semiconductors can retain their quantum phase coherence for times exceeding one second. Such long coherence times makes spins a versatile platform for exploring quantum information processing and condensed matter physics. I will discuss recent work exploiting the joint spin-state of two electrons in a GaAs double quantum dot as a spin qubit. This qubit is highly sensitive to its local magnetic environment. We leverage this sensitivity to precisely measure the statistically fluctuating nuclear polarization in the semiconductor crystal....

Decoherence and Flux Noise in Fluxonium-based Qubits

Speaker(s): 
Angela Kou
Dates: 
Thursday, October 13, 2016 - 4:00pm to 5:00pm

Superconducting qubits are created by connecting Josephson junctions, which are non-linear, non-dissipative elements,to simple electrical circuits. In this talk, I will give a brief introduction to the fluxonium qubit, which is a Josephson junction connected to a superinductance. I will then introduce an artificial molecule, composed of two strongly coupled fluxonium atoms, which possesses a tunable magnetic moment. Using an applied external flux,we can tune the molecule between two regimes: one in which the ground-excited state manifold has a magnetic dipole...

RFI: Cross Quantum Technology Systems

  • By Aude Marjolin
  • 11 July 2016

The U.S. Army Contracting Command, Aberdeen Proving Ground, Research Triangle Park Division is issuing this Request for Information (RFI) in support of the U.S. Army Research Office (ARO) and the Laboratory of Physical Sciences (LPS) in seeking information on emerging concepts and approaches for cross‐quantum‐technology systems (CQTS) that may provide a path to significantly improve the performance and functionality of individual qubit types beyond approaches focused solely on the individual qubit type. These concepts and approaches combine (hybridize) qubit types to compensate for an inadequacy in the primary qubit system, significantly improving performance of the primary qubit, or which enables new functionality in the primary qubit. This includes highly efficient, low power classical information transfer between operating domains of qubits.

Quantum Physicist Professor Rainer Blatt on the Second Quantum Revolution

  • By Aude Marjolin
  • 1 July 2016

Is quantum technology the future of the 21st century?

On the occasion of the 66th Lindau Nobel Laureate Meeting, this is the key question to be explored today in a panel discussion with the Nobel Laureates Serge Haroche, Gerardus 't Hooft, William Phillips, and David Wineland. In the following interview, Professor Rainer Blatt, internationally renowned quantum physicist, recipient of numerous honours, Council Member and Scientific Co-Chairman of the 66th Lindau Meeting, talks about what we can expect from the "second quantum revolution".

National Security Science & Engineering Faculty Fellowship (NSSEFF)

  • By Aude Marjolin
  • 22 June 2016

NSSEFF is oriented towards bold and ambitious “blue sky” research that may lead to extraordinary outcomes such as revolutionizing entire disciplines, creating entirely new fields, or disrupting accepted theories and perspectives. 

This FOA is for single investigator grant proposals for basic research in one or more technical subject categories of interest to the DoD, which includes Quantum Information Science.

Quantum Information Science

  • By Aude Marjolin
  • 20 June 2016

Quantum Information Science (QIS) supports theoretical and experimental proposals that explore quantum applications to new computing paradigms or that foster interactions between physicists, mathematicians, and computerscientists that push the frontiers of quantum-based information, transmission, and manipulation. 

Multidisciplinary Research Program of the University Research Initiative (MURI)

  • By Aude Marjolin
  • 9 May 2016

The MURI program supports basic research in science and engineering at U.S. institutions of higher education that is of potential interest to DoD.

The program is focused on multidisciplinary research efforts where more than one traditional discipline interacts to provide rapid advances in scientific areas of interest to the DoD. By supporting multidisciplinary teams, the program is complementary to other DoD basic research programs that support university research through single-investigator awards.
