Schrodinger's catapult: Launching multiphoton quantum states from a microwave cavity memory
Wolfgang Pfaff, Christopher J Axline, Luke D Burkhart +6
Encoding quantum states in complex multiphoton fields can overcome loss during signal transmission in a quantum network. Transmitting quantum information encoded in this way requir…
Micromachined integrated quantum circuit containing a superconducting qubit
T. Brecht, Y. Chu, C. Axline +6
We present a device demonstrating a lithographically patterned transmon integrated with a micromachined cavity resonator. Our two-cavity, one-qubit device is a multilayer microwave…
Suspending superconducting qubits by silicon micromachining
Y. Chu, C. Axline, C. Wang +4
We present a method for relieving aluminum 3D transmon qubits from a silicon substrate using micromachining. Our technique is a high yield, one-step deep reactive ion etch that req…
Implementing and characterizing precise multi-qubit measurements
J. Z. Blumoff, K. Chou, C. Shen +12
There are two general requirements to harness the computational power of quantum mechanics: the ability to manipulate the evolution of an isolated system and the ability to faithfu…
A coaxial line architecture for integrating and scaling 3D cQED systems
Christopher Axline, Matthew Reagor, Reinier W. Heeres +7
Numerous loss mechanisms can limit coherence and scalability of planar and 3D-based circuit quantum electrodynamics (cQED) devices, particularly due to their packaging. The low los…
A Schrodinger Cat Living in Two Boxes
Chen Wang, Yvonne Y. Gao, Philip Reinhold +13
Quantum superpositions of distinct coherent states in a single-mode harmonic oscillator, known as "cat states", have been an elegant demonstration of Schrodinger's famous cat parad…
