Entanglement doesn't need a fridge. Fragile quantum correlations surely need near-absolute-zero to survive, right? Entanglement itself doesn't.

In 2010, researchers at a Stuttgart lab asked a hard question: could you read out a single nuclear spin's state in one shot, at room temperature - not averaged, but caught in the act? Here is what the paper established.

Slow qubits are exactly what you want for memory. Nuclear-spin gates run in microseconds instead of nanoseconds, so they must be dead weight, right? Not in a hybrid architecture.

How do you create diamond NV centres? Dr. Mukesh Tripathi, Quantum Materials Scientist at XeedQ, shares his perspective. #xeedq #quantumcomputing #xq

The diffraction limit is not the wall people think it is. Light can't resolve below ~200 nm, so optically-read qubits must hit a ceiling, right? Only if readout stays linear, far-field optical microscopy. It doesn't have to.

XeedQ GmbH @xeedq-gmbh.bsky.social · 02/09/2026

In 2009, our founder Gopi Balasubramanian helped answer a question quantum computing was stuck on: can a solid-state qubit remember its state long enough at room temperature to actually be useful? Here is what the paper established.

XeedQ GmbH @xeedq-gmbh.bsky.social · 31/08/2026

The same qubit can have three different coherence times and all of them are correct. Sounds like a benchmarking contradiction, right? It isn't.

Why is it important to move early-stage quantum computers out of the lab? Florian Frank, Operations Project Manager at XeedQ, shares his perspective. #xeedq #quantumcomputing #xq

A quoted 99.9% gate fidelity is not automatically better than a quoted 99.3%. Higher number wins, right? Only if both numbers came from the same protocol.

XeedQ's quantum computers run at room temperature: 700W, using one wall socket, with the footprint of a filing cabinet, and boot in under five minutes. The power requirement shouldn't be a barrier to accessing a quantum computer. #quantumcomputing #deeptech #xeedq

A diamond qubit starts with a single atomic defect, but that's only the beginning. Where it's created, how it's controlled and how its signal is collected all matter. Here's a closer look at the engineering behind it. #xeedq #qubit #quantumcomputing

XeedQ GmbH @xeedq-gmbh.bsky.social · 11/08/2026

Colder qubits are not automatically better qubits. Indeed, the assumption that they are is intuitive: hotter means noisier, so surely a chilled quantum computer wins, right?

Five years ago, XeedQ started with a simple belief: Quantum computing should be accessible. Not someday. Now. Today, XeedQ turns 5. We brought diamond quantum computers within reach. Now, we scale it up.

The image most people have of a quantum computer is a chandelier-like machine hanging inside a dilution refrigerator, cooled to temperatures colder than outer space.

XeedQ GmbH @xeedq-gmbh.bsky.social · 12/06/2026

Here's the reality of quantum computing today. You have a job to run. You hand it to the one quantum computer you can access. It's busy? You wait. Too small? You're stuck. It doesn't have to be this way.

XeedQ GmbH @xeedq-gmbh.bsky.social · 09/06/2026

Every qubit has a clock ticking against it. Environmental noise including magnetic fluctuations, nearby nuclear spins, and vibrations gradually destroy quantum coherence. Dynamical decoupling is the technique we use to fight back.

Hochschule Karlsruhe is launching Germany's first application-oriented Bachelor's degree in Quantum Computing this winter semester, and they recently featured our own Dr. Julian Rickert, Director of Research, in a video exploring where quantum computing stands today.

XeedQ GmbH @xeedq-gmbh.bsky.social · 02/06/2026

Qubits are fragile. Noise, heat, and stray electromagnetic fields all push them toward errors. The challenge: how do you check for mistakes without collapsing the quantum state you're trying to protect?

111

XeedQ GmbH @xeedq-gmbh.bsky.social · 26/05/2026

That number, on a room-temperature diamond processor, is one most people wouldn't have predicted possible a few years ago. 99.8% single-qubit gate fidelity. Verified at Goethe University, on Baby Diamond, using QruiseOS automated calibration.

XeedQ GmbH @xeedq-gmbh.bsky.social · 21/05/2026

A recent collaboration between XeedQ, Goethe University, and Qruise hit a verified milestone on this metric. At room temperature. No cryogenics. Drop your guess below. Answer tomorrow. #nvbites #xeedq #gatefidelity #xq1 #diamondqubits

Headlines love big qubit numbers. 1,000 qubits. 100,000 qubits. A million qubits. But there's a critical distinction that rarely makes the headlines: physical qubits vs logical qubits.

111

XeedQ GmbH @xeedq-gmbh.bsky.social · 18/05/2026

Range tends to top this list, and the reasoning holds. Photon loss over fibre is a fundamental physics problem, not an engineering one you can simply spend your way out of. Quantum repeaters are the long-term answer, but they are themselves an unsolved hardware challenge.

XeedQ GmbH @xeedq-gmbh.bsky.social · 14/05/2026

Classical encryption relies on maths problems that are hard to solve. Quantum computers, at scale, could solve some of them. Quantum key distribution uses the laws of physics instead of mathematical difficulty.

XeedQ GmbH @xeedq-gmbh.bsky.social · 12/05/2026

Most people picture quantum computers as towering cryogenic machines chilled to near absolute zero. NV centres in diamond work differently.

Cloud access has its place. But it stopped being the only option a while ago. Did you get it right? #quantummyth #xeedq #xq1 #onpremisesquantum #diamondqubits

Building quantum systems takes time and careful work. Our team works with quantum systems and materials.

Classical computers struggle to simulate molecules. The number of variables grows exponentially with system size, and even a modestly complex molecule can overwhelm the world's fastest supercomputers.

XeedQ GmbH @xeedq-gmbh.bsky.social · 04/05/2026

That answer is also a deployment story. A processor that runs on standard power can go where cryogenic machines simply cannot. Physics doing the work that infrastructure used to do. #nvBites #xeedq #xq1 #greenquantum #diamondqubits

The learning curve in quantum is real. But it shouldn't be a wall. One of the biggest barriers to quantum adoption isn't the physics. It's the assumption that you need a decade of specialisation before you can do anything meaningful.

111

XeedQ GmbH @xeedq-gmbh.bsky.social · 23/04/2026

Quantum computers get the headlines. Quantum sensors are already in the field. A quantum sensor exploits superposition and entanglement not to compute, but to measure. Magnetic fields, gravitational gradients, time, rotation. All with a precision that classical instruments cannot reach.

111

XeedQ GmbH @xeedq-gmbh.bsky.social · 21/04/2026

How accurately can we read the state of an NV qubit? NV qubits are read using light. When a laser shines on them, they emit signals that depend on their state. By measuring this light, we estimate whether the qubit is in one state or another.

111

XeedQ GmbH @xeedq-gmbh.bsky.social · 16/04/2026

Can entangled particles send information faster than light? When you measure an entangled qubit, the outcome is random. You get 0 or 1 based on probabilities, but you can't control which one appears.

100

XeedQ GmbH @xeedq-gmbh.bsky.social · 14/04/2026

This is what Einstein called “spooky action at a distance.” When two qubits become entangled, they share a quantum connection. Measuring one gives information about the other, regardless of the distance between them.

Meet one of the scientists behind the work. A team built on experimental science, not assumptions.

100

XeedQ GmbH @xeedq-gmbh.bsky.social · 09/04/2026

Every quantum system needs a clear starting point. For NV qubits, this means setting them to a zero state before each run. This is done using a laser, which prepares the qubit in the desired state.

111

XeedQ GmbH @xeedq-gmbh.bsky.social · 07/04/2026

Does quantum always beat classical computing? Sorting a database? Classical computers win. Running a web browser? Classical. Playing video games, streaming video, word processing? All classical, and they'll stay that way.

100

XeedQ GmbH @xeedq-gmbh.bsky.social · 31/03/2026

In quantum systems, this is captured by a quantity called fidelity. It tells us how close a real operation is to the ideal one. For NV qubits, gate fidelity can reach around 95-99% in controlled conditions. These operations, known as quantum gates, are the basic steps behind any quantum system.

111

XeedQ GmbH @xeedq-gmbh.bsky.social · 24/03/2026

Do more qubits mean better quantum computers? A physical qubit is the actual quantum system, the NV centre, superconducting loop, or trapped ion that holds quantum information. But physical qubits make errors.

111

XeedQ GmbH @xeedq-gmbh.bsky.social · 19/03/2026

What if a coin could be heads and tails at the same time? In classical computing, a bit is definitely 0 or definitely 1. Pick one. But a qubit exists in superposition, holding both states simultaneously until measurement.
