A reset-if-leaked procedure for encoded spin qubits
Veit Langrock, David P. DiVincenzo
We report a substantially simplified procedure, based on group-theoretic reasoning, for the reduction of qubit leakage in exchange-only spin qubits. We to find exchange sequences w…
Transmon platform for quantum computing challenged by chaotic fluctuations
Christoph Berke, Evangelos Varvelis, Simon Trebst +2
From the perspective of many body physics, the transmon qubit architectures currently developed for quantum computing are systems of coupled nonlinear quantum resonators. A signifi…
Blind Oracular Quantum Computation
Cica Gustiani, David P. DiVincenzo
In the standard oracle model, an oracle efficiently evaluates an unknown classical function independent of the quantum algorithm itself. Quantum algorithms have a complex interrela…
Refuting a Proposed Axiom for Defining the Exact Rotating Wave Approximation
Daniel Zeuch, David P. DiVincenzo
For a linearly driven quantum two-level system, or qubit, sets of stroboscropic points along the cycloidal-like trajectory in the rotating frame can be approximated using the exact…
Hardware-Encoding Grid States in a Non-Reciprocal Superconducting Circuit
Martin Rymarz, Stefano Bosco, Alessandro Ciani +1
We present a circuit design composed of a non-reciprocal device and Josephson junctions whose ground space is doubly degenerate and the ground states are approximate codewords of t…
What is measured when a qubit measurement is performed on a multi-qubit chip?
Joel C. Pommerening, David P. DiVincenzo
We study how single-qubit dispersive readout works alongside two qubit coupling. To make calculations analytically tractable, we use a simplified model which retains core character…
