I am looking for someone to join me in reading and discussing the book "Theory of open quantum systems" by Breuer and Petruccione. If anyone is interested please let me know.

The thing is, I only need to know the what I must do to quickly compute brackets between multiple pauli matrices which can belong to different spaces. I looked around but it seems to be an unforgiving topic

A bit of context: I'm taking this course in quantum information and after doing the Schmidt decomposition the professor proved that a state |psi> is entangled iff the partial trace is a mixed state, but I don't understand why is that the case, because for example a state like ¼(I_A × I_B), the tensor product of the identities of the two spaces, is a separable state because I can write it as such, so it is not entangled, but the partial trace over A or B gives me ½I which is of course a mixed state. To me it look like this "theorem" works only left to right and not right to left

Is anyone related to Quantum Information Theorist here? I am curious to know about ur jobs, your researches, your prospect too.

Alice can transport a qubit perfectly to Bob via a qubit pipe at the cost of Rs10/qubit. She wishes to communicate K independent and uniformly distributed bits with 0 error. Design a protocol that can accomplish this with least cost. Prove that there exists no protocol which can accomplish the same with a stuidity lower cost .

I've done a small analysis about Quantum Entanglement with photons.

Does anyone know the probability in a Quantum Entanglement? I try to link the Bell's theorem with the real probabilities. I've called it que Quantum Wind Rose because it defines a Wind Rose with impact zones (just 3 pages).

Hello friends, my question was will Quantum Machine learning be a strong demanded field by 2030? I was think to learn it beside my uni degree so I could have chance to apply Europe to work or research in this field.

Hi all, I really wanted to know when will Quantum Communication, Cryptography or Internet will officially be on market or be used by companies. I do not want to waste my life for something that would peak around 2040 for example, that is why I am asking and contemplating my decisions.

Hello, I am a fourth-year undergraduate student starting a research project in Quantum Information.

My professor gave me a paper about the Five Open Problems in the Theory of Quantum Information, and a paper about Mutually Unbiased Measurements.

However, I had no previous knowledge of Quantum Information or Physics. I only know about Linear Algebra and some probability theory. So I have no clue about the topics in the two papers, I am currently doing the online course "Basics of Quantum Information" from IBM Quantum Learning and I would appreciate any input and advice on:

- Whether doing this research project is too much for me

- How can I learn the topics related to the research topic

- Anything that would be helpful!

I am a graduating senior that majors in computer science . I recently did a QIS internship with a national lab and I would absolutely love to explore career opportunities. I plan on going to grad school within the year . what jobs in QIS would i be able to explore with and bachelor’s in CS and what would i need to do in grad school to be able to get more opportunities in QIS

What is the significance of the 'rowsum' function in the context of stabilizer circuits, as discussed in Aronson and Gottesman's paper 'Improved Simulation of Stabilizer Circuits'? Are there any recommended resources or books that provide a detailed explanation of this function and its applications?

Hello Guys! I am starting my Masters in Physics and i want to grab a Project on Quantum Information. More specifically, Entropy and Complexity however i haven't had any contact with the "Information Theory" apart from Blundell's Thermal Physics Introduction. I am doing Information Theory Course by David Mackay. But can you guys help make a proper Road Map with Resources n all ?

Hello guys :)

I'm reading into Stochastic Masterequations right now in the context of Continuous Quantum Measurement.

I'm having a hard time understanding things, especially I'd be interested if theres a source with a nice intuitive explanation of how the stochastic terms in the equation are connected to what is experimentally recorded during the measurement that is being modeled by the SME

Any suggestions for literatur or something?

I am looking for articles, books, websites or videos on entanglement which are concise, rigorous, well written, self-contained and catered to quantum information theory. I would appreciate if anybody can drop some links.

Thank You.
