Hey, so--we cooled your boyfriend down to a hundredth of a kelvin above absolute zero. Yeah, it was so cold that all of the chemical reactions in his body ceased. Sorry. We, uh, yeah, we used him as a dielectric material in a tiny qubit. And then we quantum-entangled him with another qubit, just to see if we could. Sorry. Yeah, anyway, we thawed him out after two weeks and apparently he's doing fine now. Didn't really teach us anything about how quantum processes work in biological systems, but it sure was, uh, cool. If you'll pardon the pun.

I looove that quantum computers look, you know, LIKE THAT ™
Like a clockwork waiting to chime in a new age (or a bell who may toll for all of us).
Next step is pentagrams and runes instead of circuits.
How many angels can dance on top of a qubit chip? Immeasurable

The potential of quantum computing is immense, but the distances over which entangled particles can reliably carry information remains a massive hurdle. The tiniest of disturbances can make a scrambled mess of their relationship. To circumvent the problem, quantum computing researchers have found ways to stabilize long lengths of optical fibers or used satellites to preserve signals through the near-vacuum of space.

Updates from my Quantum Journey
It's been silent on my blog for a while now - the past year has been a busy time for me since I was working on my Master's thesis as well as working as a research assistant at Fraunhofer in parallel. Both were great experiences but it became so time-consuming that I totally lost track of posting any content on this blog!
In April 24 I finished my Master's Thesis in Physics in which I was mainly working on tensor networks. We tried to make DMRG (Density Matrix Renormalization Group) for Quantum Chemistry-like setups more efficient by lifting degeneracies in the symmetry sectors of the tensor network structure. Besides from what I learned on the physics-side of this project, it helped me to foster my fascination for method-development.
My work at Fraunhofer was very rewarding as well - I did not only learn a lot, I also had the chance to contribute in two publications in the area of quantum circuit cutting. In case you are interested, I could write a blog entry for one or both of the papers(:
During all this hard work and (to be honest) frustration and exhaustion in the past year I had this optimistic hope of doing a PhD after finishing my Master's degree. Now, this dream has become a reality and I started my PhD at the Technical University of Munich this month. I am really grateful for this oppurtunity in which I can work full-depth in the field of quantum computing - with a strong focus on software/method development. I am excited about what this journey has to offer and I am very much looking forward to it!

Scientists gain insight into the material defects that cause errors in quantum computing
A team of researchers, led by scientist Lin Zhou of Ames National Laboratory, has made important progress towards understanding the role of surface oxides in improving quantum computing circuits performance. Surface oxides are a primary cause of decoherence, or loss of quantum properties in quantum circuits. This research is discussed in two papers: "Structure and Formation Mechanisms in Tantalum and Niobium Oxides in Superconducting Quantum Circuits" is published in ACS Nano and "Exploring the relationship between deposition method, microstructure, and performance of Nb/Si-based superconducting coplanar waveguide resonators" is published in Acta Materialia. The team is part of a larger effort by the Superconducting Quantum Materials and Systems Center (SQMS) to improve quantum computers.

Quantum Computing 101: What are Qubits?
Curious about quantum computing? Let's break it down!
🔍 What’s a Qubit? A qubit is the basic unit of quantum information. Unlike classical bits (0 or 1), qubits can be 0, 1, or both at the same time thanks to a phenomenon called superposition.
✨ Why Is This Cool?
Superposition: Allows qubits to explore many possibilities simultaneously.
Entanglement: Qubits can be linked, so the state of one affects the state of another, no matter the distance.
⚙️ In Action: This means quantum computers can tackle complex problems faster by processing a huge number of possibilities at once!
Follow for more insights on the future of tech! 🚀✨

Why should you care about quantum computers?
Post #5 on Physics and Astronomy, 23/09/23
Welcome back. It’s been a while.
First, let’s backtrack. What even are quantum computers?
Today’s computers are run on bits. These are the smallest increment of data on a computer, and are run in binary–they can be in the state of either 0 or 1. This essentially corresponds to two values: off and on.
This, therefore, means that information can only remain in one, definite state.
So, what makes quantum computers so different?
A quantum computer is run on qubits (short for quantum bits). Qubits, instead of a single state, can remain in an arbitrary superposition of states (meaning it’s not in any specific state until it’s measured). Qubits, on their own, aren’t particularly useful. But it performs one, very useful, function: it can store a combination of all possible states of the qubit into one area. This means that complex problems can be represented differently in qubits compared to bits.
Quantum computers aren’t fully developed and at their full capacity quite yet. So far, there’s nothing a quantum computer can do that a regular supercomputer cannot. However, this opens an opportunity for some wonderful new things to happen.
One of these things can include the cracking of passwords.
Today’s encryption works by using “trapdoor” functions, which means that data is easy to compute in the forward direction, but extremely difficult to crack in the reverse without special keys. Keywords, ‘extremely difficult’; it is not impossible. However, this is not a massive concern: encryption works on the basis that it would simply take too long to crack.
To give you a tangible example, 100,003 and 131,071 are relatively easy to multiply together, giving you the answer 13,107,493,213. How easy, however, would it be to determine a prime factor pair of this number? It would take a computer a long time to figure this out, since it runs on bits, which can only show one definite state of data.
With quantum computers, it’s different. As aforementioned, qubits can remain in a superposition of states; somewhere in there, the desired answer lies. It’s just a matter of obtaining the resources to make this happen.
Don’t worry, though. Ordinary people aren’t at any risk quite yet.

For most of us, the passage of time flies in just one inexorable direction. But for theoretical quantum physicists, time's direction isn't quite so inflexible. It's possible to theoretically model, simulate, and observe the backwards flow of time in ways that are impossible to achieve in the real world. And now, scientists have shown that simulations of backwards time travel can help solve physics problems that cannot be resolved with normal physics. Led by physicist David Arvidsson-Shukur of Cambridge University, a team of physicists conducted an experiment in which the input state can be altered by simulating a backwards loop of time that allows them to alter the parameters after they have already been set. These loops are purely hypothetical, of course – but they can be simulated using quantum teleportation circuits created with entangled particles, in order to mathematically solve problems. "Imagine that you want to send a gift to someone: you need to send it on day one to make sure it arrives on day three," Arvidsson-Shukur explains. "However, you only receive that person's wish list on day two. So, in this chronology-respecting scenario, it's impossible for you to know in advance what they will want as a gift and to make sure you send the right one. "Now imagine you can change what you send on day one with the information from the wish list received on day two. Our simulation uses quantum entanglement manipulation to show how you could retroactively change your previous actions to ensure the final outcome is the one you want."

Spent quantum computing lecture doodling Batman characters in pure confusion.
Behold, the fruits of my labors!
Here we have Oracle, Robin V, Red Hood, Nightwing, Robin IV, and a sleeping Robin III, accompanied by something about representing complex numbers with e, phase shifts, and single-qubit gates.
Now we’re onto two-qubit gates, something about superposition, and now we have a universal gate set (which the instructor was literally grinning and laughing about). Plus Tim waking up “early” (11:46 am) and a tiny Robin hiding in Batman’s cape.
Notes about measurement collapsing the quantum state. A coin flip was mentioned, so there’s an obligatory Two-Face doodle and metaphor.
