- Novel strategies for hardware-efficient quantum processors
- Time: 12:00 pm - 1:00 pm
- Place: 5310 Chamberlin Hall
- Speaker: Harry Levine, AWS Center for Quantum Computing
- Abstract: Quantum error correction is an exciting scientific frontier at the interface of many fields including quantum information science, many-body physics, and computer science. The field has developed rapidly in the last several years, with major milestones marking the first glimpses into a future of error-corrected quantum computers. At the same time, these advances have also illuminated the major science and engineering challenges that remain on the road to useful fault-tolerant quantum computers due to large resource overheads and demanding performance and control requirements. In this talk, I will discuss recent progress in strategies to ease the demands of error correction with a focus on two leading quantum information platforms: superconducting circuits and cold atoms. First, I will discuss the paradigm of “erasure qubits” which are qubits for which errors can be flagged in real-time and are consequently easier to correct. In this context, I will discuss recent experiments showing how erasure qubits can be realized using a “dual-rail” encoding in superconducting transmons, offering a way to package standard qubit components into better error correction building blocks. Second, I will discuss the recent, rapid progress in neutral atom quantum computers and highlight how the unique capabilities for efficient and flexible control can ease the path towards scalable operation of error-corrected quantum processors. Finally, I will discuss prospects for next-generation neutral atom systems and applications in quantum error correction and precision measurement.

- Quantum Science with Ultracold Atoms: from Quantum Simulation to Quantum Networking
- Time: 12:00 pm - 1:00 pm
- Place: 5310 Chamberlin Hall
- Speaker: Elmer Guardado-Sanchez, Harvard University
- Abstract: The field of ultracold atoms is undergoing a significant transformation, evolving from primarily Analog quantum simulation to systems featuring comprehensive Digital control over all components. This advancement has enabled full coherent control over hundreds of individual atoms, opening pathways to prepare novel states of matter and positioning these systems as a credible platform for Quantum Information Processing. In this talk, I will present some of the developments in my field, illustrated through my own research. First on the Analog side, I will delve into the exciting science that a Fermionic Quantum Gas Microscope opens up to explore. This programmable quantum simulator gives unprecedented access into the microscopics of condensed matter systems. Then on the Digital side, I will talk about recent work coupling two individual atoms to a high-cooperativity cavity, highlighting how, beyond communication, optical networking nodes can also be used as mediators of entanglement. The talk will conclude with two future research directions, one focusing on a platform for next-generation quantum simulation and a second potential avenue for a scalable quantum internet using a novel atomic species.
