Quantum physics holds the promise of enhanced performance in metrology and sensing by exploiting non-classical phenomena such as multiparticle interference. Specific designs for quantum-enhanced schemes need to take into account noise and imperfections present in real-life implementations.
A half-day open house showcasing the latest developments in topological quantum materials, superconducting quantum circuits, quantum sources and detectors.
Surface acoustic waves (SAWs) are acoustic phonons that travel along the surface of a material and have been used for a wide variety of purposes, from RF filters to acoustic cavities to biosensors.
Chris Ferrie will take you through a historical journey of his own coming of age with digital software and what that experience has granted him. The lesson to be learned is that children will take advantage of the opportunities they are given, but only if their parents and teachers show genuine interest in the activities giving rise to those opportunities. 20 years from now, there will be a Quantum Technology equivalent of Bill Gates. That future leader is only a young child today.
A brief history and overview of the requirements to guide the research and development for high-coherence superconducting quantum circuits will be given. The main focus will be on materials development at NIST. Topics will include identifying and mitigating loss due to amorphous two-level systems at interfaces and how to scale the fabrication of small aluminum-oxide tunnel junctions. The junctions were studied with atom probe microscopy to get an understanding of where the oxidation occurs.
Jon Yard, IQCAbstract: Quantum-mechanical amplitudes and unitaries are typically expressed over the complex numbers. Because there is a continuum of complex numbers, classical computations of quantum systems generally utilize finite-precision approximations by rational numbers.
I give an overview of trapped ion quantum information experiments and discuss prospects for implementing multi-valued quantum logic using trapped ions.
Whenever one is tempted to employ a quantum system for any kind of applications, the focus usually lies on two properties setting it apart from a system described by a classical theory, namely the coherent superposition of different quantum states and entanglement between two ore more constituents forming the system.

We give a dissipative quantum search algorithm that is based on a novel dissipative query model. If there are $N$ items and $M$ of them are marked, this algorithm performs a fixed-point quantum search using $O(\sqrt{N/M}\log(1/\epsilon))$ queries with error bounded by $\epsilon$. In addition, we present a continuous-time version of this algorithm in terms of Lindblad evolution.
