Bias-preserving and error-detectable entangling operations in a superconducting dual-rail system
Nitish Mehta, James D. Teoh, Taewan Noh +69
For useful quantum computation, error-corrected machines are required that can dramatically reduce the inevitable errors experienced by physical qubits. While significant progress…
Demonstrating a superconducting dual-rail cavity qubit with erasure-detected logical measurements
Kevin S. Chou, Tali Shemma, Heather McCarrick +31
A critical challenge in developing scalable error-corrected quantum systems is the accumulation of errors while performing operations and measurements. One promising approach is to…
Cavity Attenuators for Superconducting Qubits
Z. Wang, S. Shankar, Z. K. Minev +3
Dephasing induced by residual thermal photons in the readout resonator is a leading factor limiting the coherence times of qubits in the circuit QED architecture. This residual the…
Generation of discord through a remote joint continuous variable measurement
E. Zalys-Geller, A. Narla, S. Shankar +5
In quantum mechanics, continuously measuring an observable steers the system into one eigenstate of that observable. This property has interesting and useful consequences when the…
Deterministic remote entanglement of superconducting circuits through microwave two-photon transitions
P. Campagne-Ibarcq, E. Zalys-Geller, A. Narla +8
Large-scale quantum information processing networks will most probably require the entanglement of distant systems that do not interact directly. This can be done by performing ent…
3-Wave Mixing Josephson Dipole Element
N. E. Frattini, U. Vool, S. Shankar +3
Parametric conversion and amplification based on three-wave mixing are powerful primitives for efficient quantum operations. For superconducting qubits, such operations can be real…
Continuous quantum nondemolition measurement of the transverse component of a qubit
U. Vool, S. Shankar, S. O. Mundhada +9
Quantum jumps of a qubit are usually observed between its energy eigenstates, also known as its longitudinal pseudo-spin component. Is it possible, instead, to observe quantum jump…
Robust concurrent remote entanglement between two superconducting qubits
A. Narla, S. Shankar, M. Hatridge +8
Entangling two remote quantum systems which never interact directly is an essential primitive in quantum information science and forms the basis for the modular architecture of qua…
Comparing and combining measurement-based and driven-dissipative entanglement stabilization
Yehan Liu, Shyam Shankar, Nissim Ofek +6
We demonstrate and contrast two approaches to the stabilization of qubit entanglement by feedback. Our demonstration is built on a feedback platform consisting of two superconducti…
The reconfigurable Josephson circulator/directional amplifier
K. M. Sliwa, M. Hatridge, A. Narla +4
Circulators and directional amplifiers are crucial non-reciprocal signal routing and processing components involved in microwave readout chains for a variety of applications. They…
Confining the state of light to a quantum manifold by engineered two-photon loss
Zaki Leghtas, Steven Touzard, Ioan M. Pop +12
Physical systems usually exhibit quantum behavior, such as superpositions and entanglement, only when they are sufficiently decoupled from a lossy environment. Paradoxically, a spe…
Tracking Photon Jumps with Repeated Quantum Non-Demolition Parity Measurements
L. Sun, A. Petrenko, Z. Leghtas +11
Quantum error correction (QEC) is required for a practical quantum computer because of the fragile nature of quantum information. In QEC, information is redundantly stored in a lar…
Stabilizing entanglement autonomously between two superconducting qubits
S. Shankar, M. Hatridge, Z. Leghtas +7
Quantum error-correction codes would protect an arbitrary state of a multi-qubit register against decoherence-induced errors, but their implementation is an outstanding challenge f…
In-Plane Magnetic Field Tolerance of a Dispersive Aluminum Nanobridge SQUID Magnetometer
N. Antler, E. M. Levenson-Falk, R. Naik +4
We characterize the flux sensitivity of a dispersive 3D aluminum nanobridge SQUID magnetometer as a function of applied in-plane magnetic field. In zero field, we observe an effect…
