Reconstructing Quantum Dot Charge Stability Diagrams with Diffusion Models
Vinicius Hernandes, Joseph Rogers, Rouven Koch +5
Efficiently characterizing quantum dot (QD) devices is a critical bottleneck when scaling quantum processors based on confined spins. Measuring high-resolution charge stability dia…
Running a six-qubit quantum circuit on a silicon spin qubit array
I. Fernández de Fuentes, E. Raymenants, B. Undseth +9
The simplicity of encoding a qubit in the state of a single electron spin and the potential for their integration into industry-standard microchips continue to drive the field of s…
Two-qubit logic and teleportation with mobile spin qubits in silicon
Yuta Matsumoto, Maxim De Smet, Larysa Tryputen +6
The scalability and power of quantum computing architectures depend critically on high-fidelity operations and robust and flexible qubit connectivity. In this respect, mobile qubit…
Unified evolutionary optimization for high-fidelity spin qubit operations
Sam R. Katiraee-Far, Yuta Matsumoto, Brennan Undseth +9
Developing optimal strategies to calibrate quantum processors for high-fidelity operation is one of the outstanding challenges in quantum computing today. Here, we demonstrate mult…
Near-Term Spin-Qubit Architecture Design via Multipartite Maximally-Entangled States
Nikiforos Paraskevopoulos, Matthew Steinberg, Brennan Undseth +4
The design and benchmarking of quantum computer architectures traditionally rely on practical hardware restrictions, such as gate fidelities, control, and cooling. At the theoretic…
Modeling and Experimental Validation of the Intrinsic SNR in Spin Qubit Gate-Based Readout and Its Impacts on Readout Electronics
Bagas Prabowo, Jurgen Dijkema, Xiao Xue +3
In semiconductor spin quantum bits (qubits), the radio-frequency (RF) gate-based readout is a promising solution for future large-scale integration, as it allows for a fast, freque…
