The New Quantum Era - innovation in quantum computing, science and technology

Title: Molecular and Subatomic Physics with David MazziottiDescription: Welcome to another episode of The New Quantum Era Podcast hosted by Kevin Rowney and Sebastian Hassinger. Today, they are joined by David Mazziotti, a physicist, and research team leader at the University of Chicago. He generously showed up with some deeply fascinating material for your consideration. Professor Mazziotti is a highly accomplished scholar, researcher, and mentor. This interview with David is a ringside seat on one of the most interesting recent research on molecular and subatomic physics that is now being explored by scholars using quantum computers. Today, David talks about how he got interested in quantum computing, his current findings and experiments, and his optimistic perspective about the possibility of breakthroughs in the near future of quantum.Key Takeaways:[6:13] David talks about his background.[11:32] David’s first professor role was teaching quantum chemistry.[12:30] David speaks about the first time he used quantum computing hardware to perform experimentation, like simulation of quantum chemistry.[14:42] David Talks about his first foray into quantum computing.[16:45] What measurements is David doing inside the quantum computer to register that data on the polytopes?[18:58] Where did the inspiration come from for using limited hardware with limited capabilities (from a gate and noise perspective) in a really creative way to do really sophisticated simulations? [24:19] What are the major engineering or commercial applications?[28:43] David talks about his collaboration on a couple of papers on a generalizable system for free a simulation of open quantum systems.[31:24] Is there something that can be done on a standard quantum computer to simulate open systems? Is new hardware needed?[33:40] Is it possible for David to speculate if there will be brand new algorithmic breakthroughs for clever classical optimization problems? [35:10] David shares the publication of  a new paper on communications physics.[37:15] Can we make progress with noisy quantum computers?[40:39] David speaks about how he and his team ended up getting a spectrumscoptic noise “fingerprint” of each of their IBM Quantum computers on which they were doing an experiment. What does derive from the spectrum of the QC?[42:28] Is David  programming the pulses or is he using gates?[43:42] Is the fingerprint like a qubit? [45:22] David believes that a more holistic perspective on the noise could be the way to control noise better.[48:30] David’s work has been on superconducting hardware, is it applicable to  trapped ions or neutral atoms or Rydberg atom systems that are coming out in the next year? And hopefully to photonic systems down the road? [49:46] Is David’s work on superconducting hardware applicable to quantum sensing devices?[52:41] David shares his excitement about the evolution of quantum computing in the next couple of years.[56:19] For listeners who want to explore  some of the code and are qiskit literate? Is any of the stuff that David has  mentioned available open source style? [59:05] David speaks of his work on reduced density matrix theory. [1:00:26] If David could wish for any new hardware in the next year, what would he want? [1:04:53] Sebastian  and Kevin share their insights from a mind blowing conversation with David Mazziotti.Mentioned in this episode:Visit The New Quantum Era PodcastLearn more about David Mazziotti’s work at his group’s website and check out their github repoTweetables and Quotes:“So a polytope is basically a convex object with a bunch of flat sides and on one side, there's this polytope that's forbidden, on the other side, one that's allowed, and then there's this hyperplane in the middle called the Borland-Dennis Inequality, and you just don't want the points to go through.”  — David Mazziotti“In superconductivity, electrons form Cooper pairs, and these Cooper pairs of electrons all end up in a global quantum state and that allows you to send electricity into the superconductor, and actually have a current then come out from a macroscopic distance away, but not have any loss due to friction because you're really sending an electron into a global quantum state that's entangled with the electron that's coming out on the other side at the same time.”  — David Mazziotti“It's only after 2000, that people were able to realize excitation condensates by pumping them with light with radiation. And then in the last few years, since 2017, they've been able to prepare them in the laboratory, even without pumping them with radiation, either using strong magnetic fields or, actually, in some cases, not using any magnetic fields at all. But using Creative Chemistry.” — David Mazziotti“The quantum computer  gives one an ability  to look at some things that before were really more just a theoretical dream” — David Mazziotti“Can we make progress with noisy quantum computers? I think that's one of the central questions, because ultimately, quantum computers are always going to be somewhat noisy to some extent.” — David Mazziotti

 Welcome to another episode of The New Quantum Era Podcast hosted by Kevin Rowney and Sebastian Hassinger. Today, they are joined by Cesar A. Rodriguez  Rosario, Chief Scientific Officer at Strangeworks, who is discussing the parallels between quantum computing and the development of the classical computing world at the stage of vacuum tubes and the invention of the transistor.Cesar Rodriguez is a great example of somebody who is knowledgeable about the space of Quantum Computing and sees its possibility but he's got a decent level of guarded optimism and even skepticism on some of these results, which sometimes run fits and starts and sometimes even go backward.Key Takeaways:[4:33] Cesar shares what brought him into Quantum Computing.[5:35] Cesar talks about his academic background[11:39] Coming from computer engineering and having an unconventional journey through quantum physics, does Cesar consider he has a different perspective on the field today? [15:28] Given the current stage of technology, what does Cesar think of the role of foreign theorists? [17:37] How does Cesar view the reliability and the breakthrough potential of the currently existing crop of algorithms given the current limits?[18:57] Cesar explains what QUantum Advantage is.[21:08] From the landscape of the current algorithms out there, does  Cesar feel like there's an imminent breakthrough in these scare algorithms? [23:05] Will there going to be more "dequantized" algorithms?[24:35] Cesar shares what he calls Quantum Value.[25:21] Looking at the theory landscape, what are the most exciting things to Cesar?[29:20] Does everything still fit into the general buckets of VQE and QAOA? Are there other categories that are emerging that are distinct enough from those two approaches that they have their own acronym yet?[30:52] What does quantization mean?[33:49] Cesar explains why quantum computers are fundamentally better at some problems than classical computers.[37:33] Cesar defines the molecular geometry problem[39:50] Cesar speaks of the beginning of Quantum Computing.[42:53] Cesar talks about a recent major breakthrough.[45:48] Cesar talks about the complexity of photonics.[48:28] Cesar shares the challenge of speed.[52:10] Kevin and Sebastian share the highlights of an interesting conversation with Cesar A. Rodriguez Rosario.Resources:Visit The New Quantum Era PodcastGoogle's 2019 quantum supremacy experimentA classical attack on Google's supremacy claimAn overview of Quantum supremacyThe variational quantum eigensolver algorithm paper from Alan Asperu-Guzik's group at HarvardEddie Farhi and Jeffrey Goldstone's Quantum Approximate Optimization Algorithm paperNature paper on error correction on spin qubits in diamondThe Chip, by T. R. Reid is a terrific book for understanding the early history of classical computing. 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
