I have been going through the introductory IBM Quantum Learning course "Use a Quantum Computer Today", specifically the "Quantum Computing Context" lesson.

While the lesson covers optimization and mapping business constraints into quantum-ready formulations, Quantum-Inspired Optimization (QIO) as an active, standalone commercial model is not really clear or emphasized. The text frames computing as a binary between classical CPUs and hybrid QPU workflows, missing the middle layer of QIO. I only learned about how QIO operates in practice after searching for it by myself.

Through Quantum-Inspired Optimization (QIO), European companies like Multiverse Computing (based in San Sebastian, Spain) have built successful revenue-generating products using tensor networks and QUBO (Quadratic Unconstrained Binary Optimization) formulations on classical GPU clusters today. They deliver massive performance jumps for finance and logistics without requiring physical quantum hardware.

For those active in the industry, is Quantum-Inspired Optimization considered a fringe byproduct in the quantum community, or is it actually the primary working commercial standard today while we wait for fault-tolerant hardware? If QIO on classical GPUs is currently one of the main ways these mathematical formulations generate real enterprise value, why is it not highligthed as a working business model in this quantum learning intro?

Will this IBM Qsikit developer certification course be useful if QIO is what I want to do in the financial sector until quantum hardware becomes more stable?

Hello.

I thought I would ask for other peoples input on this topic as it is fairly subjective. I know that western quantum computing software companies can be quite strict with their approach to IP and sometimes refuse to hire Chinese or Russian nationals for this reason. I was wondering if having any experience at a company in China as European/US citizen would be seen as an issue when applying for western companies later in life ? Apologies, if this is a silly question.

This material covers the fundamental concepts of symmetries, conservation laws, constants of motion, and Noether's theorem in quantum mechanics, presenting detailed mathematical derivations and step-by-step examples accessible even to beginners.

Understanding Quantum Technologies is probably the best reference for quantum technologies and is now in it's 9th edition. In this interview Olivier explains the process and his motivation. The interview is recorder for The Quantum Factor, a LinkedIn page dedicated to quantum mechanics.

While learning quantum computing with Qiskit, I wanted to make working with Bell states and analyzing CHSH inequality results a little more straightforward.

BellBox provides reusable functions for creating Bell states, changing measurement bases, analyzing quantum correlations, and calculating CHSH values, with tests and runnable examples.

It's not a replacement for Qiskit, just a small tool that makes these specific tasks easier to reuse.

I'd appreciate feedback from people working with quantum computing. What would make a tool like this more useful?

This webinar may be particularly relevant to electrical and telecommunications engineering students, researchers, and professionals interested in photonics, optical networks, quantum technologies, and communication systems.

I’m helping with outreach for this event and thought it might be useful to share with people interested in these fields.
Feel free to share it with anyone who might be interested!

I myself have recently graduated with Master's Degree in Quantum Tech; I did research related to Trapped ions. However, finding a job looks more impossible than ever, especially without a PhD or experience. (UK)

Can you share your story of how you found your job in the Quantum field? Any advice for the young people?

Francis Halzen realised that ice at the South Pole could be used to track particles known as neutrinos. His vision and scientific leadership have been fundamental for the IceCube Neutrino Observatory – a cubic kilometre of ice that is equipped with light sensors. Using IceCube, researchers can capture neutrinos from extremely energy-rich processes in the distant universe.

Neutrinos are everywhere, but they do not make themselves known. They pass all the way through the Earth and through our bodies without us noticing. Very rarely, a single neutrino will interact with an atomic nucleus, which makes it possible for someone with the right equipment to discover them.

Scientists have long known that the cosmos contains natural particle accelerators, which fire out particles with energies up to a million times more than can be achieved in laboratories on Earth. Much about these sources is mysterious: what are they, where are they, and what are the main processes inside them?

Neutrinos with extremely high energies are created in the same environments as other types of particles. However, unlike other particles, neutrinos reach us without changing direction or losing energy. This means they can provide information that is not available in any other way.

Francis Halzen first presented his vision for capturing neutrinos at the South Pole in 1988. When a neutrino collides with an atomic nucleus, it produces a flash of light that can be tracked by sensors in the clear glacial ice. The South Pole’s ice has many advantages, as it is free from various types of interference and the area is geologically stable, with no earthquakes. Halzen and his idea soon gained the support of other researchers and, just a few years later, preliminary testing was conducted on sensors in ice.

Cosmic neutrinos with extremely high energies are very rare, so an enormous volume of ice is needed to observe an adequate number of collisions. IceCube covers an entire cubic kilometre and was finished in 2011. Researchers soon discovered the first high-energy neutrinos and, a few years later, could publish their discovery of neutrinos that must originate far outside our solar system. The search for the universe’s neutrino sources could begin in earnest.

“Francis Halzen has led an international team of researchers and engineers who have provided us with a fantastic instrument. His tenacity and scientific vision has paved the way for a new kind of astronomy,” says Mark Pearce, Chair of the Nobel Committee for Physics.

The neutrino interactions that are continuously collected by IceCube will provide researchers with novel knowledge about the violent settings in which high-energy neutrinos can be created – and could even reveal previously unknown cosmic phenomena.

This material is designed to be accessible to first- and second-year undergraduate students by providing full mathematical derivations without omitting intermediate steps.
Furthermore, deliberate effort has been made to establish a a natural bridge connection between mathematical physics and quantum mechanics.

I am trying to understand why the pauli exclusion principle is true, which requires understanding why fermions are anti symmetric. I understand mathematically the square of the wave function and the negative wavefunction must be equal, and the swapping can only involve a 1 or -1. My issue is, multiplying the wavefunction by negative 1 means a different wave doesn’t it? Trying to look this up I get explanations that particles with half integer spin do not rotate completely when rotated 360 degrees, but we aren’t talking about rotating, we’re talking about swapping. Pchem was a struggle for me and I find myself looking back on material not understanding the physical implications of the math.

hi guys! anyone else looking to join masters degrees in quantum computing/technology/information in the 2027 fall session? im very lost and just looking for some sort of support group of people going through the same with how frustrating all of this is.

a person who don't know a lot abt quantum computing,

does he can persue a phd or he have to do a master first

Which should I go for a research career?

Like pursuing a phd.

Hey y'all. I'm new here. Any idea about QC relatively new projects/startups that need more people onboard???

i have experience in cs and c++ so i can do programming as well

This material explains Spin Precession and the Energy-Time Uncertainty Principle through a concrete example. I've laid out the derivations in detail step-by-step so that even undergraduate students can easily follow and fully understand the concepts.
I checked this document many times, but there might still be some typos. Thank you for understanding! I hope this helps you.

I graduated as a computer scientist and I have a deep passion for quantum computing. I have an AI paper already published in a Q1 journal and currently in the process of publishing two quantum computing papers. I have also done a math minor with the thesis being on relativistic quantum mechanics. Right now I want to apply for a masters or a PhD in quantum computing. I did not have much luck in the previous cycle (being an international student in need of funding) but I am now trying again. I currently word as a grad TA in the mean time and got myself a good research position but in CS and Mathematics. In your experience, how can I make my profile more attractive to universities: are there any trainings or more papers I need to write. I am open to your suggestions and I welcome any advice or recommendations you have.
Thank you!
