Descripción del proyecto
Lograr la escalabilidad en computación cuántica
Exponencialmente más rápidos que los ordenadores convencionales, los ordenadores cuánticos universales podrían ser más adecuados para las soluciones avanzadas y de investigación científica. Pueden ayudar a los científicos a resolver muchos desafíos sociales en materia de salud, energía y cambio climático. Antes de materializar la tecnología cuántica, es necesario abordar cuestiones relativas a la fragilidad y escalabilidad del cúbit, la unidad básica de la tecnología cuántica. El proyecto TOPSQUAD, financiado con fondos europeos, espera cambiar el «statu quo». Impulsará la computación ofreciendo un sistema topológicamente protegido y extraordinariamente estable y escalable con múltiples cúbits. El proyecto establecerá estados topológicos que no se verán afectados por la descoherencia para abordar la fragilidad del cúbit. Además, resolverá la cuestión de la escalabilidad mejorando la integración a escala de oblea gracias al uso de procedimientos compatibles con CMOS.
Objetivo
Our vision is to enable the world of quantum computing through an unprecedented stable and scalable many-qubit system. This platform will allow us to establish important scientific breakthroughs such as the observation of Majorana bound states, which can lead to the new field of non-Abelian many-body physics.
A universal quantum computer can be exponentially faster than classical computers for certain scientific and technological applications. This long-awaited innovation can help solve many global challenges of our time related to health, energy and the climate, such as quantum chemistry problems in order to design new medicines, material property prediction for efficient energy storage, big data handling problems, needed for complexity of climate physics.
Such a quantum computer has not yet been realized because of qubit fragility and qubit scalability. The output of TOPSQUAD lays the foundation for universal quantum computing with stable and scalable qubits:
We will address qubit fragility by creating topological states, which are insensitive to decoherence. We will address qubit scalability by developing waferscale fabrication technology, using CMOS-compatible processes. After TOPSQUAD, existing integrated-circuit technology can then serve to scale up from individual qubits to 100,000s.
These two approaches have not been combined within a single system, but our recent results show that we can be the first to address the key challenges:
1. For the first time we will synthesise Ge wires on silicon wafers using scalable CMOS-compatible processes.
2. We will devise an unprecedented silicon system with the required topological properties: Ge wires with a silicon shell.
3. The thin Si shell will suppress metallization, thus avoiding the destruction of topological states by proximity-induced superconductivity, a typically overlooked problem.
With this, TOPSQUAD can realize a scalable, CMOS-compatible, topologically protected system.
