#Introduction
I work on quantum technologies for networks & sensing. Mostly playing with quantum optics & quantum information.
I work at the University of Geneva in Switzerland & previously studied at the University of Queensland in Australia.
I was the inaugural chair of the Strategic Research Agenda Work Group for the European Quantum Flagship initiative & founding Editor-in-Chief for the IOP journal: Quantum Science and Technology.
In #quantumInformation often implementation estimates arise by counting options available for each of a number of qubits.
For example, if each #qubit is in a definite state |0〉 or |1〉 then there are 2ᴸ such configurations for 𝐿 qubits. If we are able to at will apply 𝑋,𝑌 or 𝑍 operations to each qubit then there are 4ᴸ such operations.
(If you do something on some qubits and nada on others then it's still a distinct operation jointly, so there are 4, not 3, options for each qubit)
How much is that?
A quick upper bound can be obtained by taking 2³=8<10 .
So for example for 𝐿=9 qubits if we want to run a protocol starting from every single configuration of definite qubit states (eg process tomography) then we will have to run it no more than thousand 10³ times. And so quickly you get an idea about what is much and what is too much.
More general operations can be decomposed into 𝑋,𝑌 or 𝑍 (and nothing, so the identity). During my PhD I was working with Marcel Goihl who was running a lot of numerics for a #quantum model of insulation arising from disorder. We were looking for charges that would get stuck and thus not participate in conductance. For transport through 𝐿=9 qubits we'd have 4⁹=2¹⁸=10⁶ million contributions that we'd need to calculate.
For 𝐿=13 this becomes 2²⁶<10⁹ contributions.
Marcel got curious that this is quite many and how much energy his calculations used on an #hpc cluster. Running a typical idea check quickly amounted to the yearly budget of a statistical German person.
He now works at a CO2 offsetting company and before graduating wrote with Ryan Sweke the proposal to keep track of what's the #enviroment cost of our calculations in #physics
re-#introduction after moving instances
Hello mathstodon!
We are a computational #quantum #physics group at the Freie Universität Berlin and the Dahlem Center for Complex Quantum Systems.
Our research interests are in the #QuantumControl of atoms, molecules and condensed matter systems with an #AMO like structure as well as #QuantumInformation processing.
We are using both #CoherentControl concepts and #OptimalControl theory, applying them to isolated as well as open quantum systems.
The development of optimal control methods is a major part of our work. A current emphasis is on control methods for open quantum systems.
We collaborate with research groups all over Europe (France, Spain, Switzerland), Israel and the US.
Thanks for having us, we are looking forward to sharing and discussing research updates!

Here's an #introduction of @frederikhahn as part of my agenda that #nice should be a characteristic demanded of academics.
In the past few years Freddy has been gently cracking his head on how to remove bottlenecks in a #quantumNetwork. He focused on relevant #quantum states and tweaked their parts like he tweaks parts in his bike to make it run seamlessly
https://arxiv.org/abs/1805.04559
(Local complementations interest me for #quantumCompiling: the unitary encoding the repetition code can be turned into a gate between any two qubits because one can distill Bell pairs out of #GHZ states.)
Rick came from Berlin to the #quantumInformation #workshop in #benasque by train. His tap water canister was half empty: he realized that meh whatev he can travel half Europe and not eat if the food is not what he wants provided he has water to last him even more than 24 hs.
Frederik is a scientist who leads by example, is sustainably concerned about the #climateCrisis but look at him shining. His #intermittentFasting skills allowed him to be chilled after a strainous long distance travel but I learn from him that being nice and chilled is a muscle we can all train.
His integrity at work reminds me that it's not impossible to keep our humanity first and also excell at research. I wish we had an equivalent of #citationMetrics for acts of kindness in academia.
These photos were taken on a Friday, on Monday that week he defended his thesis. In style, which is his style. For his #phd hat I'd add a phone charger, his daily cycling suffices to top up the battery. I don't know how to symbolize my thanks for having made my local science world wholesome, one #introvert thought at a time, but: thank you for caring, Dr Hahn!
interesting paper today on #arxiv

Introductory post here after making the decision to migrate away from the bird site. I’m a #physicist with a broad range of interests but mostly working on the foundations of #quantummechanics #relativistic #quantuminformation and formal models of #consciousness. I am fascinated by the nature of #time (I teach a whole class on it) and the connections between #complexity and #emergence. I also love #geology oddly enough.
In case you are like me interested in #quantumcomputing #quantumcomputer #quantum #quantuminformation #qkd and similar topics, I have collected some links that maybe help you to find new contacts to follow.
Additions are welcome. Would like to see a growing quantum curious community

A belated #introduction post! I'm a science journalist covering theoretical #computerscience for Quanta Magazine.
I focus on #quantuminformation, #algorithms, computational #complexity, and the theory of #MachineLearning. (Historically I've been averse to hashtags, but I'll get used to it.
I'm new to this beat (Until this fall I covered physics), but you'll be seeing my first CS stories very soon!
so because Im fairly new on this instance I thought I`ll finally write an #introduction toot.
I am Florian, a german #physics master #student working in the field of #quantum #optics. i did some programming in the past as a hobby, now mostly just #python for studying.
Some other interests are:

#fitness

How can we make the most of noisy, current-generation quantum computers, and just what is the Error Correction Zoo? Take a listen to find out!
In Episode 1 we talked to Dr Yihui Quek about what #information means.
How do we understand the process of #learning, and what does it have to do with #QuantumComputers? Take a listen to find out!
What challenges are involved in interfacing a #quantumcomputer with a conventional #supercomputing facility?
Here's what this week's guest, Dr Alba Cervera-Lierta of the Barcelona Supercomputing Center and Quantum Spain, had to say!

I don't know if I've just not found it yet, but there's an abysmally low representation of #quantuminformation and #quantumcomputing people here, on scholar.social and my federated timeline. Most people who I see active are from #astronomy.
