Quantum Computer Controlled by Superconducting Digital Electronics at Millikelvin Temperature
Caleb Jordan, Jacob Bernhardt, Joseph Rahamim +16
Current superconducting quantum computing platforms face significant scaling challenges, as individual signal lines are required for control of each qubit. This wiring overhead is…
Entanglement-assisted Quasi-cyclic Quantum Low-density Parity-check Codes over Qubits
Pavan Kumar, Abhi Kumar Sharma, Karthik Bharadwaj +1
We construct several families of entanglement-assisted quasi-cyclic quantum LDPC (EA-QC-QLDPC) codes via structured tilings of permutation matrices. The entanglement-unassisted por…
Observation of quantum many-body effects due to zero point fluctuations in superconducting circuits
Sebastien Leger, Javier Puertas-Martinez, Karthik Bharadwaj +11
Electromagnetic fields possess zero point fluctuations (ZPF) which lead to observable effects such as the Lamb shift and the Casimir effect. In the traditional quantum optics domai…
Fabrication and characterization of aluminum SQUID transmission lines
Luca Planat, Ekaterina Al-Tavil, Javier Puertas Martinez +10
We report on the fabrication and characterization of 50 Ohms, flux-tunable, low-loss, SQUID-based transmission lines. The fabrication process relies on the deposition of a thin die…
Fast high fidelity quantum non-demolition qubit readout via a non-perturbative cross-Kerr coupling
R. Dassonneville, T. Ramos, V. Milchakov +12
Qubit readout is an indispensable element of any quantum information processor. In this work, we experimentally demonstrate a non-perturbative cross-Kerr coupling between a transmo…
