Quobly Marks Significant Progress in Reliable Quantum Computing Solutions

Quobly’s Quantum Leap

Meet Quobly, the French startup that’s shaking things up in the world of Quantum Computing. They’ve recently made waves by announcing that FD-SOI technology could be the key to making quantum computers not just a sci-fi dream, but a reality. By utilizing traditional semiconductor manufacturing fabs and collaborating with CEA-Leti’s R&D pilot line, Quobly is paving the way for commercial quantum computing that could actually scale.

The Semiconductor Revolution

You might wonder, what’s the big deal about semiconductors? Well, the semiconductor industry has been the backbone of classical computers, enabling them to get faster and cheaper over the years. Now, it seems that same industry holds the potential to do the same for quantum computers. Imagine being able to harness the power of silicon spin qubits—they’re not just a fancy term; these little guys are crucial for achieving fault-tolerant, large-scale quantum computing. They boast impressive clock speeds measured in microseconds, and they can perform one and two-Qubit gate operations with a fidelity of over 99%. Talk about precision!

Going Fabless

Quobly has taken an innovative approach by adopting a fabless model. This means they’re focusing on design and innovation while relying on established semiconductor giants like STMicroelectronics, GlobalFoundries, and Samsung to handle the manufacturing. By leveraging FD-SOI—a commercially available CMOS technology—Quobly is not just riding the quantum wave; they’re setting the stage for a future where quantum computing is both commercially viable and cost-effective.

Breaking Down the Challenges

At the recent IEDM event on December 9th, 2024, Quobly launched some exciting developments that tackle the critical challenges of scaling quantum systems. Partnering with CEA-Leti, CEA-IRIG, and CNRS, they’ve demonstrated essential building blocks for a quantum computer based on commercial FD-SOI. Here’s what they’ve been up to:

–

Low-Temperature Operations

: They’ve fine-tuned the digital and analog performance of their systems, adhering to rigorous circuit design guidelines.
–

Single Qubit Operations

: Using both hole and electron spin qubits, they’ve made strides in manipulating qubits at impressive speeds. The ambipolar platform they’ve developed optimizes performance by leveraging the long coherence times of electrons for memory and the strong spin-orbit interaction of holes for speedy data processing.
–

Charge Control

: They’ve achieved significant advancements with commercial GF 22FDX, which helps define a standard cell for a two-qubit gate.

Key Achievements That Matter

So, what does all this mean in practical terms? Here are some of Quobly’s standout achievements:

–

Cryogenic Control Electronics

: They’ve reached a voltage gain of up to 75dB, with noise levels at an astonishingly low 10-11 V²∙μm²/Hz. Plus, they’ve managed to keep the threshold voltage variability down to just 1.29 mV∙μm.
–

Ambipolar Spin Qubits

: Quobly has successfully co-integrated hole and electron qubits on FD-SOI technology. They can manipulate holes at a speed of 1μs and achieve a coherence time of 40μs for electrons using Hahn echo techniques.
–

Two-Qubit Gate Standard Cell

: They’ve demonstrated double quantum dot operations, showcasing the potential of commercial FD-SOI in real-world applications.

A Bright Future for Quantum Computing

With these advancements, Quobly is not just positioning FD-SOI as a critical player in the realm of scalable quantum processors. They’re establishing themselves as a leader in cost-efficient, fault-tolerant quantum computing. By bringing together quantum and classical components on a single platform, Quobly is crafting the future of scalable Quantum System on Chip (QSoC) architectures.

As we stand on the brink of this quantum revolution, one has to ask: are we ready for a world where quantum computing becomes as ubiquitous as our smartphones? Quobly seems determined to make that future a reality.
