Anthropic’s Claude Mythos 5 has developed a quantum circuit design that uses 17 times fewer gates than an earlier approach.
The findings suggest automated circuit design could accelerate progress toward practical quantum computing.
Rethinking quantum circuit design Quantum computers process information through qubits, which can represent combinations of states through superposition.
Engineers must therefore make quantum circuits as efficient as possible.
Classical computers can efficiently execute this method, but translating it into quantum circuits creates a major storage problem.

Such improvements substantially reduce the quantum resources that useful applications require, so practical quantum computers could arrive sooner than previously anticipated.
(Similar to ordinary computers, quantum computers work by applying a long sequence of simple operations, called gates, to their qubits.
At one extreme, a quantum circuit can uncompute intermediate results as soon as they have been used.
This is what makes quantum circuit design an especially interesting test of Claude’s capabilities.
So, we asked Claude to design a more efficient quantum circuit for the decoding step.

Google has verified a technology called "magic state cultivation" on its Willow processor, which has drastically reduced the quantum error rate.
It is understood that in quantum computing, photons (or light particles) are used as qubits.
However, qubits are prone to frequent errors, so quantum computers still have limitations at present.
"Magic states" are the key element to realize universal quantum computing.
Moreover, generating magic states with a sufficiently low error rate has long been a major challenge in building practical large-scale systems.

But the quantum states behind their incredible computing power are also exceptionally fragile, and keeping errors under control is a monumental task.
To address this problem, physicists invented something called "magic states" – quantum states prepared in advance that allow computers to perform difficult quantum operations without compromising their error correction.
In 2024, Google researchers started working on an idea called magic state cultivation.
The idea isn't necessarily to produce a better magic state than conventional methods can, but to produce one of comparable quality using fewer resources.
Using magic state cultivation, the researchers reduced errors in the preparation process by a factor of around 40, producing magic states with a fidelity of at least 99.99 percent.

MIT’s new qubit architecture is enabling faster, more accurate quantum computing operations.
Researchers at MIT have developed a superconducting qubit architecture designed to address one of the key engineering challenges facing scalable quantum computing: achieving both long coherence times and rapid, reliable interactions with the rest of a quantum system.
A dedicated data mode stores quantum information, while an arm mode provides the strong interactions needed to communicate with other qubits and electronic components.
Nonlinear coupling is important because it enables changes in one quantum component to influence another, forming a basis for many quantum operations.
Simulation results showed the arm qubit outperforming other superconducting qubit architectures, combining long coherence with faster operations and readout.

Google researchers reduced errors in a crucial quantum computing resource about 40-fold, demonstrating a method that could lower the hardware demands of useful, error-corrected machines.
Ultimately, then, this looks to be an important, incremental advance toward practical quantum computing that demonstrates a way to prepare essential quantum states with fewer errors and potentially lower hardware demands.
Why Magic States Matter Quantum computers process information using qubits, which are vulnerable to disturbances that can corrupt a calculation.
The technique, called logical state tomography, estimates a quantum state by combining measurements taken in different ways.
The observed logical error rate was about seven times higher than predicted by simulations, according to the supplement.

Google says its Willow quantum chip has cut errors about 40-fold when preparing special states used in quantum calculations, tackling a costly step toward building machines powerful enough to crack bitcoin wallets.
Spending typically reveals the public key, while some payment types expose it from the start.
Some later payment formats hide the public key behind a hash, a digital fingerprint, until the owner spends.
Those units then need the digital equivalent of fuel to run certain operations, specially prepared quantum states that researchers call “magic states.”
In a quantum computer, hardware devoted to producing magic states is hardware that cannot be assigned to other work.

For years, federal agencies have treated quantum technology as something to prepare for, not something to put to work.
Putting quantum to work At The Forge, Accenture Federal Services’ facility in Washington, D.C., agency teams get hands-on experience with a commercial quantum computer.
“A quantum computer is not just a faster computer,” Patterson said.
“A quantum computer works differently, so you need to understand what kind of workloads within your mission to give to a quantum computer.”

Google Quantum AI has demonstratively opened up a key bottleneck in quantum computing: we’ve shown that “magic state cultivation” works in practice on our Willow processor, reducing errors about 40x compared to without it.
This breakthrough, published today in Science, is a crucial step towards scaling up quantum computing to practical use.
The "magic state" bottleneck Since 2004, long before quantum computing was a practical engineering pursuit, researchers have foreseen a particularly tricky bottleneck.
To achieve “universal” quantum computing and execute useful programs, you need to be able to run (and error-correct) a specific set of quantum operations.
An extra challenge is that once you use a magic state, you can’t re-use it, making magic states a scarce resource.

To overcome errors, the machines need to tap into so-called magic states—and scientists at Google Research think their quantum chip could help get them there.
The standard recipe to make magic states is called distillation, and it creates fewer, more accurate quantum states from many imperfect ones.
“You can have up to 95 percent of your quantum computer being spent just generating these high-fidelity magic states,” Rosenfeld says.
Using Google’s Willow chip, Rosenfeld’s team encoded a rough magic state in a few qubits and then measured it.
which collapses the quantum state to either of those two options, the team asked, “Are you the right magic state: yes or no?”

Today, Zurich Instruments announced the ZQCS Quantum Control System, a next-generation platform to operate large-scale quantum computers.
It is engineered to tackle the pivotal challenge on the path to fault-tolerant quantum computing: building long-lived logical qubits.
Image Credit: Zurich Instruments AG Physical qubits are fragile; noise and drift can erase quantum information in microseconds.
The remedy is to use logical qubits, which encode quantum information across many physical qubits, thereby enabling error correction.
The ZQCS is the control system built to meet these needs, uniting scalable direct-RF electronics, deterministic real-time networking, and powerful software.

It also enables standard computers to perform Gaussian boson sampling, a simulation used to demonstrate the capabilities of photonic quantum computers.
Quantum computers are devices that use quantum principles to perform calculations, potentially tackling problems beyond the capabilities of even the most advanced conventional supercomputers.
Their work focuses on Gaussian boson sampling, a computational task associated with photonic quantum computers.
By reducing the resources needed for quantum simulations, the algorithm offers researchers a more practical route to investigating complex quantum devices.
Its further development could help make detailed modelling more widely accessible as scientists work towards larger and more reliable quantum computers.

What Quantum Computers Will Deliver, and Where the Hype Begins What will quantum computers actually bring people?
Quantum computers can simulate highly complex systems such as molecules in a way that is extremely difficult for classical computers.
Jan Henrik Leisse: Quantum computers are complex systems with highly specialized components, and of course there are international supply chains.
Jan Henrik Leisse: If technology isn’t competitive, “Made in Europe” won’t help in the long run.
