This quantum jewel consumes almost nothing: a breakthrough that ridicules the superordinators and redefines the computing power

Quantum computers, long considered as machines of the future, are becoming a tangible reality thanks to major innovations. Northern quantum, a Canadian startup, recently made a significant announcement in the field of quantum computer science. The company has developed an integrated qubit with an error correction, an advance that could drastically reduce the size and energy consumption of quantum computers. This technology promises to transform the computer landscape by offering unrivaled performance while minimizing the energy imprint.

A revolutionary technological advance

North quantum has designed a qubit which directly integrates the error correction, thus eliminating the need for massive clusters of physical qubits. This innovation solves a major problem of quantum computer science : Maintaining the integrity of quantum information over time. Qued, extremely sensitive to disturbances, generally require sophisticated error correction techniques. Traditionally, this implies the combination of many physical qubits to create a single logical qubit, thus increasing the complexity and energy consumption. However, the quantum north system uses a single physical component capable of assuming the role of a logical qubit, thus simplifying architecture.

The heart of this innovation is based on a superconductive bosonic resonator, which stores quantum information in the form of light particles (photons). By distributing information through several modes within the same physical structure, what can identify and correct certain types of interference. This approach, called multimodal coding, gives each qubit an internal breakdowns tolerance, reducing the need for external error correction.

Energy and size implications

A quantum computer built on quantum north architecture could occupy only 20 square meters and consume a fraction of the energy used by current high performance systems. Researchers believe that such a system could solve complex problems, such as deciphering an 830 -bit RSA key in an hourby consuming only 120 kilowatt hours of energy. By way of comparison, a supercomputer would require nine days and 280,000 kilowatt hours to accomplish the same task. These figures highlight the energy efficiency and the power of this new technology.

The future of quantum computer science

North Quantum plans to market a machine of 100 logical qubits by 2029, with a complete system of 1,000 logical qubits provided for 2031. The company highlights the reduced size and low energy consumption of its machines as major assets for high performance calculation centers (HPC), where energy costs are a constant concern. Julien Camirand Lemyre, Director General of Nord Quantum, said that multimodal coding allows the construction of quantum computers with excellent error correction capacitieswithout the burden of additional physical qubits.

The use of the “bosonic code” Tesseract further strengthens tolerance to the system’s breakdowns by protecting from current quantum faults such as Bit inversions, phase inversions and control errors. This innovative approach could transform the way in which quantum computers manage errors, making these machines more reliable and effective.

Challenges and perspectives for the years to come

Despite the impressive progress made by quantum north, several challenges remain. The scale of this technology to reach 1,000 logical qubits will require continuous advances in terms of materials and cooling techniques. Maintaining the stability of qubits over long periods remains a major obstaclealthough preliminary tests have shown promising results. The company filtered approximately 12.6 % of the executions where the qubit did not behave as expected, but managed to preserve the quantum state through 32 cycles of error correction without measurable degradation.

While North Quantum advances towards its ambitious objectives, a question remains: how will this revolutionary technology be integrated into existing IT infrastructure, and will what new horizons open for technological innovation?
