The History of Superconducting Qubits with Steve Girvin
The New Quantum Era
10/24/22 • 58 min
Welcome to another episode of The New Quantum Era Podcast hosted by Kevin Rowney and Sebastian Hassinger. Today, they are joined by Steve Girvin, professor of Physics at Yale who has a central role in the Yale Quantum Institute, which has been ground zero for the recent development in superconducting qubits.
The topics we had initially planned needed some adjustment, because on the day of the interview, the Nobel Prize in Physics was awarded to three scientists for their work experimentally verifying the theory behind entanglement, the source of much of quantum computing's power. Alain Aspect, John F. Clauser, and Anton Zeilinger were recognized for their experiments in an area that has broad implications for secure information transfer and quantum computing.
Sebastian, Kevin, and Steve have an interesting talk about some of the history of the superconducting qubits and the transmon in particular, which is a basis for most of the modern superconducting qubits on the market. They also cover the topic of diversity, quality, and inclusion.
Key Takeaways:
[3:43] Steve introduces himself.
[5:23] Steve shares his primary domains of research.
[9:50] Was there a sort of self-awareness in the Yale group that Steve and his team were taking radically? Were they considering a different approach that could solve some of the challenges of the other models that existed at the time?
[14:38] Steve talks about how relatively quickly the hardware can be fabricated to be able to crank out, iterations, variations, and experiments.
[17:27] Is there room for optimism about the new dimensions of research related to MER material science?
[19:25] Steve shares his thoughts on the news about the 2022 Nobel Prize in Physics.

[25:38] Steve addresses how hard it is to predict the future.
[27:21] Does Steve consider himself an optimist about the progress of quantum computing?
[30:10] How can we get reliable performance out of an inherently, very unreliable system?
[33:22] Steve helps us fill in the narrative, in the history of where GKP codes are situated and their significance to contemporary developments.
[41:14] Steve talks about the basic steps of the algorithm to do the error correction.
[44:01] The history of computer science is very, uh, white, male, and, uh, dominated in nature, Steve shares his thoughts about diversity, equity, and inclusion.
[48:34] What we can do to change the composition of the field when the underlying foundations of the way science is done in the lab have a such rigid history of hierarchy, power structures, and power dynamics that are so easily abused?

The Fault-Tolerance Threshold with Dorit Aharonov
The New Quantum Era
04/24/23 • 66 min
Welcome to another episode of The New Quantum Era Podcast hosted by Kevin Rowney and Sebastian Hassinger.
In this episode, we are joined by Dorit Aharonov, a professor at the Hebrew University of Jerusalem and one of the pioneers of quantum computing. She's also the Chief Science Officer at QEDMA, a quantum startup based in Israel. Dorit is one of the major movers and shakers of quantum error correction and co-author of the important Threshold Theorem for quantum error correction. Kevin, Sebastian, and Dorit talk about her recent work on the theoretical foundations of random circuit sampling.
Key Takeaways:
[4:22] Dorit shares her path into quantum information and computing.
[8:27] Dorit explains the threshold theorem in an easy-to-understand manner.
[16:35] The velocity of error correction versus the generation of errors in the computation could depend on physical implementation, or the algorithm. Maybe even both.
[18:53] A more powerful assertion Dorit makes is that there's a deeper connection between the phases of matter and the transition between solid and liquid and these quantum error correction thresholds.
[19:51] A lot of the foundations of classical error correction were laid down in the mid-40s in Von Neumann's work when the IAS system was being built. Dorit still sees the echoes of that.
[22:35] We might be witnessing a growing momentum around the powerful expression of new quantum error correction technologies.
[25:28] Dorit talks about the difference between error mitigation and error correction.
[26:55] Dorit explains the idea of the reset gate.
[30:22] It might be safe to say that challenges are primarily engineering in nature and that we have enough science to enable that engineering to get to fault tolerance.
[31:50] Dorit discusses a possible timeline for this engineering to get to fault tolerance.
[34:07] Is Dorit an NISQ optimist or a pessimist when it comes to real-world applications?
[39:21] Dorit addresses the difference between practical and asymptotic quantum advantage.
[41:30] Dorit shares what the paper on random circuit sampling shows.
[45:25] Dorit explains why the machine learning algorithms that were dequantized are treacherous.
[49:56] Dorit shows optimism regarding the possibility of seeing evidence of a quantum event.
[52:25] Dorit admits to finding constructive interference between working in the industry and working on theoretical questions.
[53:50] Is there something Dorit is excited about in the next year or two that will be another step forward?
[56:50] Dorit talks about concrete examples of experiments and sensors that might be arriving thanks to quantum computing advancements.
[1:00:35] Sebastian and Kevin share the highlights of a fantastic conversation with Dorit.

Tweetables and Quotes:
“Nobody actually believed that it was possible to correct errors that occur on quantum states because of the lack of reversibility. ” — Dorit Aharonov
“it's a physics phenomenon... below a certain threshold, we can think of this as if the system is capable of some completely different behavior, like ice and water. It's just like a phase transition -- below that, there would be macroscopic entanglement and ... ability to control large scale quantum correlations. And above it, this would not be possible.” — Dorit Aharonov

Tweetables and Quotes:
“You can use some qubits and their quality is really, really good. You can connect them very, very efficiently, and you can connect as many as you want, in a way that scales, we have to do all those things... and nobody has cracked the code for all these bullet points.” — Cesar A. Rodriguez Rosario
“Ideally, what's going to happen is that once we have the scalable error corrected qubits and all that, then you don't have to be a theorist anymore, and then I'm going to be a full-time quantum engineer and that will be healthy, I want that to happen since that would mean that the industry succeeded.” — Cesar A. Rodriguez Rosario
“It's okay, that things are not useful, yet, there's nothing wrong with that, because we're still working towards that.” — Cesar A. Rodriguez Rosario
Dawning of the Era of Logical Qubits with Dr Vladan Vuletic
The New Quantum Era
02/12/24 • 44 min
Kevin and Sebastian are joined by Dr. Vladan Vuletic, the Lester Wolfe Professor of Physics at the Center for Ultracold Atoms and Research in the Department of Physics at the Massachusetts Institute of Technology
At the end of 2023, the quantum computing community was startled and amazed by the results from a bombshell paper published in Nature on December 6th, titled Logical quantum processor based on reconfigurable atom arrays in which Dr. Vuletic's group collaborated with Dr Mikhail Lukin's group at Harvard to create 48 logical qubits from an array of 280 atoms. Scott Aaronson does a good job of breaking down the results on his blog, but the upshot is that this is the largest number of logical qubits created, and a very large leap ahead for the field.

Black hole physics and new states of quantum matter with John Preskill
The New Quantum Era
08/24/23 • 62 min
If anyone needs no introduction on a podcast about quantum computing, it's John Preskill. His paper "Quantum Computing in the NISQ era and beyond," published in 2018, is the source of the acronym "NISQ," for Noisy, Intermediate Scale Quantum" computers -- basically everything we are going to build until we get to effective error correction. It's been cited almost 6000 times since, and remains essential reading to this day.
John is a particle physicist and professor at Caltech whose central interests are actually cosmology, quantum matter, and quantum gravity -- he sees quantum computing as a powerful means to gain more understanding of the fundamental behavior of our universe. We discuss the information paradox of black holes, quantum error correction, some history of the field, and the work he's doing with his PhD student Robert (Hsin-Yuan) Huang using machine learning to estimate various properties of quantum systems.

Tweetables and Quotes:
“The idea that you can solve problems efficiently that you'd never be able to solve because it's a quantum world and not a world governed by classical physics, I thought that was one of the coolest ideas I'd ever encountered.” — John Preskill
“There's something different about quantum information than ordinary information. You can't look at it without disturbing it.” — John Preskill
“Ideas which were being developed without fundamental physics, necessarily in mind, like quantum error correction, have turned out to be very relevant in other areas of physics.” — John Preskill
“Thinking about quantum error correction in the context of gravitation led us to construct new types of codes which weren't previously known. “ — John Preskill
“With quantum computers and quantum simulators, we can start to investigate new types of matter, new phases, which are far from equilibrium.“ — John Preskill.
