SESSION 1: Nanomechanics and Superconducting QIP
Session Chair:
4:00pm-4:45pm	Raymond Simmonds, National Institute of Standards and Technology
	Quantum-based Measurements with Superconducting Circuits
	Abstract. Over the last decade, superconducting circuits have shown rapid progress in being implemented for quantum-based measurements. This includes the advent of superconducting qubits, high quality-factor resonant electromagnetic cavities, and high-Q mechanical resonators. Combinations of these circuit elements could lead to a quantum information processor, the ability to simulate quantum systems, or quantum-limited measurements. I will discuss efforts at NIST to develop these circuit elements and describe some of our recent experimental results.
4:45pm-5:15pm	Emily Pritchett, University of Waterloo, Institute for Quantum Computing
	General-Purpose Quantum Simulation with Prethreshold Superconducting Qubits
	Abstract. We introduce a protocol for the fast simulation of n-dimensional quantum systems on n-qubit quantum computers with tunable couplings. A mapping is given between the control parameters of the quantum computer and the matrix elements of an n -dimensional real (but otherwise arbitrary) Hamiltonian that is simulated in the n-dimensional single-excitation subspace of the quantum simulator. A time-dependent energy/time rescaling minimizes the simulation time on hardware having a fixed coherence time. We demonstrate how three tunably coupled superconducting phase qubits can simulate a realistic three-channel molecular collision using this protocol. The method makes a class of general-purpose time-dependent quantum simulation practical with today's sub-thershold-fidelity qubits.
