Systematic Construction of Time-Dependent Hamiltonians for Microwave-Driven Josephson Circuits
Yao Lu, Tianpu Zhao, André Vallières +13
Time-dependent electromagnetic drives are fundamental for controlling complex quantum systems, including superconducting Josephson circuits. In these devices, accurate time-depende…
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…
A high on-off ratio beamsplitter interaction for gates on bosonically encoded qubits
Benjamin J. Chapman, Stijn J. de Graaf, Sophia H. Xue +12
Encoding a qubit in a high quality superconducting microwave cavity offers the opportunity to perform the first layer of error correction in a single device, but presents a challen…
Energy-participation quantization of Josephson circuits
Zlatko K. Minev, Zaki Leghtas, Shantanu O. Mundhada +3
Superconducting microwave circuits incorporating nonlinear devices, such as Josephson junctions, are one of the leading platforms for emerging quantum technologies. Increasing circ…
The Kerr-Cat Qubit: Stabilization, Readout, and Gates
Alexander Grimm, Nicholas E. Frattini, Shruti Puri +6
Quantum superpositions of macroscopically distinct classical states, so-called Schrödinger cat states, are a resource for quantum metrology, quantum communication, and quantum comp…
Experimental implementation of a Raman-assisted six-quanta process
S. O. Mundhada, A. Grimm, J. Venkatraman +9
Nonlinear processes in the quantum regime are essential for many applications, such as quantum-limited amplification, measurement and control of quantum systems. In particular, the…
To catch and reverse a quantum jump mid-flight
Z. K. Minev, S. O. Mundhada, S. Shankar +6
Quantum physics was invented to account for two fundamental features of measurement results -- their discreetness and randomness. Emblematic of these features is Bohr's idea of qua…
Pair-cat codes: autonomous error-correction with low-order nonlinearity
Victor V. Albert, Shantanu O. Mundhada, Alexander Grimm +3
We introduce a driven-dissipative two-mode bosonic system whose reservoir causes simultaneous loss of two photons in each mode and whose steady states are superpositions of pair-co…
Generating higher order quantum dissipation from lower order parametric processes
S. O. Mundhada, A. Grimm, S. Touzard +4
Stabilization of quantum manifolds is at the heart of error-protected quantum information storage and manipulation. Nonlinear driven-dissipative processes achieve such stabilizatio…
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…
