Quantum basement lab: I visited the group of @AndreasAtETH in Zürich today and got to see their 30 meter long tube for transmitting quantum microwave signals, all cooled down to reduce noise.

We have a new preprint on the #arxiv:

https://arxiv.org/abs/2308.00968

On the #physics side, we explore the non-Hermitian phases of density correlations in condensates of #light.

Methodically, we introduce a field-theory technique known as “pseudo-particles”, which, to my knowledge, has not been applied to open #quantum systems so far. Among other things, we hope that this method could also help to better model #qubits with non-Markovian noise.

#ITByte: #Quantum #Circuits are the way programs are expressed on a quantum computer.

In simplest terms, quantum circuits are a sequence of matrix operations performed on #Qubits, the quantum version of a bit.

Why Qubit Connectivity Matters https://thequantuminsider.com/?p=2356330 #Insights #connectivity #Qubit_connectivity #qubits #QuEra #Yuval_Boger #quantumdaily By Yuval Boger Chief Marketing Officer, QuEra Computing Inc Qubit connectivity is a crucial aspect of quantum computing because it determines how qubits can interact with each other. This interaction is necessary for performing quantum operations and executing quantum algorithms. Here are a few reasons why qubit connectivity is important:

Hej, everyone! Just migrated here, so I figure it's #introduction time :)

I'm Alexander, a theoretical physics student at TU Berlin. Currently I'm finishing my master's thesis in computational physics at @QuControlBerlin on #Quantum #OptimalControl of superconducting #qubits, mainly looking at universal sets of gates on transmons coupled via a tunable bus.
So, mostly trying to get my #Fortran and #Python code to bend to my will...

Y aquí nos encontramos nuevamente con mis viejos amigos: LEX y YACC. El reto en esta ocasión es hacer un parser para el lenguaje ensamblador de un próximo procesador de spin #qubits.

Por cierto una de las mejores cursos sobre este tema lo recibí en la #UCA por un maestro estrella: Alfonso Abarca.

Hoy nos visitó un investigador de Sandia National Labs en EEUU para explicarnos la novedosa técnica que usan para caracterizar #qubits en silicio.

Es una impresionante combinación de matemática abstracta con estadística avanzada para encontral el mejor modelo que explica la fuentes de ruido y su proporción en la perturbación total.
