Josephson Microwave Sources Applied to Quantum Information Systems

Adam J. Sirois, Manuel C. Castellanos Beltran, Anna E. Fox, Samuel P. Benz, Peter F. Hopkins
Quantum computers with thousands or millions of qubits will require a scalable solution for qubit control and readout electronics. Colocating these electronics

Calibration of free-space and fiber-coupled single-photon detectors

Thomas Gerrits, Alan L. Migdall, Joshua C. Bienfang, John H. Lehman, Sae Woo Nam, Oliver T. Slattery, Jolene D. Splett, Igor Vayshenker, Chih-Ming Wang
We present our measurements of the detection efficiency of free-space and fiber-coupled single- photon detectors at wavelengths near 851 nm and 1533.6 nm. We

Electron-electron interactions in low-dimensional Si:P delta layers

Joseph A. Hagmann, Xiqiao Wang, Ranjit V. Kashid, Pradeep N. Namboodiri, Jonathan E. Wyrick, Scott W. Schmucker, Michael D. Stewart, Richard M. Silver, Curt A. Richter
Key to producing quantum computing devices based on the atomistic placement of dopants in silicon by scanning tunneling microscope (STM) lithography is the

Materials loss measurements using superconducting microwave resonators

Corey Rae H. McRae, Haozhi Wang, Jiansong Gao, Michael R. Vissers, Teresa Brecht, A Dunsworth, David P. Pappas, J. Mutus
The performance of superconducting circuits for quantum computing is limited by materials losses. In particular, coherence times are typically bounded by two

Notes on Interrogating Random Quantum Circuits

Luis Brandao, Rene C. Peralta
Consider a quantum circuit that, when fed a constant input, produces a fixed-length random bit- string in each execution. Executing it many times yields a

Overlap junctions for superconducting quantum electronics and amplifiers

Mustafa Bal, Junling Long, Ruichen Zhao, Haozhi Wang, Sungoh Park, Corey Rae H. McRae, Tongyu Zhao, Russell Lake, Daniil Frolov, Roman Pilipenko, Silvia Zorzetti, Alexander Romanenko, David P. Pappas
Due to their unique properties as lossless, nonlinear circuit elements, Josephson junctions lie at the heart of superconducting quantum information processing

Atomic-scale control of tunneling in donor-based devices

Xiqiao Wang, Jonathan E. Wyrick, Ranjit V. Kashid, Pradeep N. Namboodiri, Scott W. Schmucker, Andrew Murphy, Michael D. Stewart, Richard M. Silver
Atomically precise donor-based quantum devices are a promising candidate for scalable solid- state quantum computing. Atomically precise design and

Dielectric loss extraction for superconducting microwave resonators

Corey Rae H. McRae, Russell Lake, Junling Long, Mustafa Bal, Xian Wu, Battogtokh Jugdersuren, Thomas Metcalf, Xiao Liu, David P. Pappas
The investigation of two-level-state (TLS) loss in dielectric materials and interfaces remains at the forefront of materials research in superconducting quantum

Hybrid integrated quantum photonic circuits

Ali Elshaari, Wolfram Pernice, Kartik A. Srinivasan, Oliver Benson, Val Zwiller
Recent development in chip-based photonic quantum circuits has radically impacted the ways in which we can process quantum information. However, it is

Parallel Device-Independent Quantum Key Distribution

Rahul Jain, Carl A. Miller, Yaoyun Shi
A prominent application of quantum cryptography is the distribution of cryptographic keys that are provably secure. Such security proofs were extended by

Auto-tuning of double dot devices it in situ with machine learning

Justyna P. Zwolak, Thomas McJunkin, Sandesh Kalantre, J. P. Dodson, E. R. MacQuarrie, D. E. Savage, M. G. Lagally, S N. Coppersmith, Mark A. Eriksson, Jacob M. Taylor
The current practice of manually tuning quantum dots (QDs) for qubit operation is a relatively time- consuming procedure that is inherently impractical for
