A team at the Advanced Quantum Testbed at Berkeley Lab (in collaboration with UC Berkeley and Yale) developed an architectural blueprint for a novel quantum processor based on fluxonium qubits, which outperform the most widely used superconducting qubits. Furthermore, they simulated two types of logic gates to validate the performance ...

Durante cuatro años, AQT ha liderado avances experimentales significativos, y en una amplia gama de temas.

By Monica Hernandez Since its foundation, the Advanced Quantum Testbed (AQT) was commissioned as an open platform to explore and define the future of superconducting quantum computers end-to-end, from quantum processor technology to quantum algorithms. In collaboration with AQT’s expert team, testbed users will have full access to hardware and ...

Ferschweiler, a rising senior, spent two months at AQT working in collaboration with the Quantum Nanoelectronics Laboratory at the University of California at Berkeley.

Researchers at the Advanced Quantum Testbed (AQT), in partnership with the startup Super.tech (acquired by ColdQuanta), demonstrated how a smart compiler specifically tailored for superconducting hardware can optimize circuits, gates, and networks and execute less error-prone quantum algorithms such as Quantum Approximate Optimization Algorithm (QAOA).

Three research teams at DOE national laboratories have offered their perspectives about conducting their novel research as part of the AQT user program.

One of three awardees for this year, Hashim is part of the research team at the Advanced Quantum Testbed (AQT) at Lawrence Berkeley National Laboratory (Berkeley Lab)

Acceptance certificate signed after delivery and commissioning of the Raith EBPG 5150. The machine’s self-calibration protocol, combined with exceptional environmental stability, provides highly reproducible lithography.

First wafer probed using the newly delivered automated probe station. This tool allows us to gather statistics on a significantly larger number of junctions per wafer.

Junction fabrication process is ported to a new oxygen plasma asher. This new tool significantly simplifies the process, improves critical current uniformity, and improves the uniformity of how the junctions age with time.

Simulations of two qubit gate dynamics have illustrated the well known trade-off between coherent and incoherent errors as a function of gate speed. Faster gates are less susceptible to the incoherent error caused by qubit relaxation, while slower gates have lower levels of coherent error due to unwanted interactions with ...

Randomized Benchmarking (RB) is a standard experiment to quantify the error rate of a quantum gate set. In addition to being relevant for building fault-tolerant quantum computers, reducing two-qubit gate error rates enables the execution of NISQ algorithms with larger-depth. However, environmental drift is a ubiquitous phenomenon in quantum hardware, ...
