1:45pm - 2:30pm | Matthew Neeley, Google Scaling superconducting qubits: Toward a demonstration of quantum supremacy | Abstract. Our group has proposed an experiment to demonstrate "Quantum Supremacy", using a quantum device to perform a well-defined computational task that cannot be done in reasonable time on even the largest classical supercomputers (arXiv:1608.00263). This will require a device with 49 qubits arranged in a 7-by-7 grid and one- and two-qubit gate error rates below about 0.1%. I will outline our experimental progress toward this goal and describe the challenges associated with scaling superconducting qubit devices to the level of several tens of qubits and beyond. |
2:30pm - 3:00pm | Karl Mayer, CU Boulder; NIST Faithful conversion of propagating quantum bits to mechanical motion | Abstract. Electromechanical devices are emerging as quantum information processing elements for superconducting circuits. By using a mechanical oscillator parametrically coupled to a microwave resonant circuit, these devices can store, amplify, and frequency-convert microwave fields. Experimental efforts to convert microwave fields to mechanical motion have so far been mostly limited to Gaussian states, such as coherent or squeezed states. We present experiments that demonstrate and characterize the conversion of non-Gaussian states, namely propagating microwave qubits prepared in mixed single-photon and superposition states. We perform state tomography to infer the density matrices for both the input states and the mechanical states after conversion, and compute the average fidelity for this conversion process to be in excess of 80%. |
