Chip-to-chip entanglement of transmon qubits using engineered measurement fields
C. Dickel, J. J. Wesdorp, N. K. Langford +6
While the on-chip processing power in circuit QED devices is growing rapidly, an open challenge is to establish high-fidelity quantum links between qubits on different chips. Here,…
Benchmarking non-simulable quantum processes via symmetry conservation
Tobias Chasseur, Felix Motzoi, Michael Kaicher +2
As quantum devices scale up, many-body quantum gates and algorithms begin to surpass what is possible to simulate classically. Validation methods which rely on such classical simul…
High-fidelity Rydberg quantum gate via a two-atom dark state
David Petrosyan, Felix Motzoi, Mark Saffman +1
We propose a two-qubit gate for neutral atoms in which one of the logical state components adiabatically follows a two-atom dark state formed by the laser coupling to a Rydberg sta…
Linear and logarithmic time compositions of quantum many-body operators
Felix Motzoi, Michael Kaicher, Frank Wilhelm
We develop a generalized framework for constructing many-body-interaction operations either in linear time, or in logarithmic time with a linear number of ancilla qubits. Exact gat…
Optimized cross-resonance gate for coupled transmon systems
Susanna Kirchhoff, Torsten Keßler, Per J. Liebermann +4
The cross-resonant gate is an entangling gate for fixed frequency superconducting qubits introduced for untunable qubits. While being simple and extensible, it suffers from long du…
