Real-time dynamics of lattice gauge theories with a few-qubit quantum computer

Physicists in Innsbruck have realized the first quantum simulation of lattice gauge theories, building a bridge between high-energy theory and atomic physics. In the journal Nature, Rainer Blatt's and Peter Zoller's research teams describe how they simulated the creation of elementary particle pairs out of the vacuum by using a quantum computer.


Welcome Tyler Malloy!

Tyler is a visiting student from the University of British Columbia in the program Cognitive Systems: Computer Science and Design. He will stay in our group for seven months and work on the new experiment control software TrICS as a software developer.


Welcome Milena Guevara-Bertsch!

Welcome! Milena Guevara-Bertsch has joined the group as a PhD student. Milena got her master's degree at the University of Costa Rica. During her thesis, she designed and built a Zeeman slower for applications of optical lattices in solid state physics.

Here in Innsbruck, she will work in the Precision project with optical clocks based on trapped aluminium ions.

Realization of a scalable Shor algorithm

Shor’s algorithm is likely the most famous quantum algorithm. It solves a centuries-old problem, namely the factoring of numbers into primes. Physicists led by Rainer Blatt joined forces with scientists at MIT, led by Isaac Chuang, to efficiently implement Shor’s algorithm in an ion-trap based quantum computer. Here their approach can be directly applied to larger numbers.

Welcome! Lukas Gerster has joined the group as a PhD student

Lukas did his master's thesis in Jonathan Home’s trapped ion group at the ETH in Zurich. During his thesis, he worked on spectral filtering and laser diode injection for multi-qubit trapped ion gates.

In Innsbruck, Lukas has joined the SQIP project, which aims at implementing a scalable trapped ion quantum computing architecture.

Welcome! Heng Shen has joined the group as a Postdoc

Heng has just received his PhD in the Niels Bohr Institute, Copenhagen, where he worked in Eugene Polzik's group. During his thesis work, he generated spin-squeezed states of room-temperature atomic ensembles and used them to enhance the sensitivity of a magnetometric measurement. He also demonstrated deterministic continuous variable teleportation between two ensembles. In our group, he will be working in the quantum simulation team at the IQOQI.

Bernardo Casabone receives his PhD
