DECODE QUANTUM

Welcome to the 76th episode of Decode Quantum. In our series of episodes recorded in Lindau where dozens of physics Nobel laureates meet with young scientists, we picked a few of them who are specialized in the broad field of quantum computing to head their thoughts about it, Caroline Tornow, Francesca Pietracaprina, Yaroslav Herasymenko and Adam Shaw.

This podcast was recorded on July 1st, 2024, in Lindau, Germany during the Lindau Nobel Laureate Meetings 2024 with Fanny Bouton (OVHcloud) and Olivier Ezratty.

Caroline Tornow is from ETH Zurich and just started a PhD in the Condensed Matter Theory and Metamaterials group. Beforehand, during her Master’s in Quantum Engineering at ETH, she worked in the Quantum Computational Science group at IBM Research Zurich and the Quantum Information Theory group at ETH. She therefore has some ideas on where we are with regards to the maturity of quantum computing in general, and, we would guess, also with superconducting qubits.

Francesca Pietracaprina is a software engineer and researcher at Algorithmiq, a quantum computing software company based in Helsinki Finland. She did her PhD in between statistical and quantum physics and two postdocs in Rome and Toulouse where she focused on localization in quantum systems, a phenomenon that involves a breakdown on thermalization in presence of strong disorder. She then obtained a Marie Curie fellowship with which she moved to Dublin and continued her research on quantum disordered systems and quantum thermodynamics. At Algorithmiq, she is focused on creating full stack solutions for drug discovery and simulation.

Yaroslav Herasymenko is a post-doc at TU Delft and at QuSoft in Amsterdam. He did his PhD at the University of Leiden. He currently works on the development of fermionic (in other words, of electrons) quantum simulations.  He started to work in condensed matter theory and then became interested in math and computing methods of condensed matter. It drove him to the field of quantum computing. He is a native from Kyiv, Ukraine.

Adam Shaw has a PhD in physics in 2024 from Caltech, where he studied quantum computing with Rydberg atom arrays. He is part of the team who broke recent records with the control of 6,100 atoms using lasers, working on both experimental and theoretical aspects to these systems, working on gate fidelities, large scale quantum simulation, and showing how certain quantum errors can be erased. He is now a post-doc at Stanford, still working on cold-atoms computing.

Welcome to the 75th episode of the Decode Quantum podcast. In our series of episodes recorded in Lindau where dozens of physics Nobel laureates met with young scientists, we had a chance to meet Bill Phillips, who is one of them, after the first episode with David Wineland.

This podcast was recorded on July 1st, 2024, in Lindau, Germany during the 73rd Lindau Nobel Laureate Meeting 2024.

Bill Phillips is American physicist from the same generation as Alain Aspect. He got his PhD in physics at the MIT working on nuclear magnetic resonance on the magnetic moment of the proton in H2O. He later did some work with Bose–Einstein condensates and then worked at NIST. There, he developed (actually, used) a technique to trap cold atoms in vacuum using lasers, called the Magneto-Optical Trap (MOT), in connection with an idea from Jean Dalibard, who was our previous guest. Bill is also a professor of physics at the University of Maryland. He was a laureate from the Nobel prize in physics in 1997 along with Steven Chu and Claude Cohen-Tannoudji, at the relatively early age of 49, by today’s standards. It was for his work on the Zeeman slower and other techniques related to the cooling and trapping of atoms. He was also participating in the panel on the future of quantum computing with Olivier Ezratty at the Lindau conference. By the way, his mother was Italian, and he happens to speak French.

The transcript from the podcast published on Olivier Ezratty’s website has been edited by Bill Phillips and Olivier Ezratty. It is slightly different from the podcast audio recording to clarify the discussion content.

Welcome to the 75th episode of the Decode Quantum podcast. In our series of three episodes recorded in Lindau where dozens of physics Nobel laureates were gathered with young scientists, we had a chance to meet David Wineland.

This podcast was recorded on July 1st, 2024, in Lindau, Germany during the 73rd Lindau Nobel Laureate Meeting.

David Wineland is an American physicist currently at the University of Oregon who is specialized in atomic physics, and in particular, uses laser-cooled trapped ions to implement the elements of quantum-computing. He became a laureate of the Nobel prize in physics in 2012 along with Serge Haroche of Ecole Normale Supérieure and Collège de France, Paris. He received his PhD in physics from Harvard University in 1970 on a topic we’ll see later in our discussion. He was then a post-doc at the University of Washington where he worked on electrons in ion traps. In 1975, he joined the National Institute of Standards and Technology (NIST) where he created a group working on ion storage and was also an academic at the University of Colorado, Boulder. He and his colleagues were among the first {laser cooling was demonstrated at the same time by the group of Peter Toschek in Heidelberg} to laser-cool ions in 1978 and then demonstrated other optical techniques to control ions and implement the first two-qubit logic gate in 1995. He and colleagues also worked on the creation of the most precise atomic clock using quantum logic on a single aluminum ion in 2019. The 2005 experiment was the first demonstration of quantum-logic spectroscopy. The most precise quantum logic clock using an Al+ (aluminum) ion was demonstrated in 2019. This work later contributed to the creation of trapped ion quantum computers from the companies IonQ and Quantinuum.
