Quantum computing

Room-temperature quantum computing

Quantum systems, such as quantum bits (qubits), to measure physical quantities with improved precision.


NV-centers in Quantum computing

Quantum sensing refers to the use of quantum systems, such as quantum bits (qubits), to measure physical quantities with improved precision beyond what is possible using classical methods. Quantum computing, on the other hand, is the use of quantum systems to perform computations beyond the capabilities of classical computers. Quantum supremacy is the point at which quantum computers can outperform classical supercomputers in certain applications. Entangling scalable amounts of qubits to achieve quantum supremacy is not trivial - the gate model of quantum computing for example requires more error correction. The challenge is to have high accuracy at room temperature.

Potential solution

Diamond-based quantum sensors as a solution

NV-centers in diamonds are attractive candidates for qubits, the basic unit of information in a quantum computer because they can be easily controlled and manipulated using optical techniques.

Quiet vacuum like environment

Diamond has a large band gap and can be enriched with "quiet" nuclei such as ¹²C. Therefore it is almost a vacuum-like environment ideal for qubits to entangle with minimal noise.

Long coherence times at room temperature

The long coherence times of the electron spin states associated with NV centers at room temperature makes them resistant to decoherence and an ideal candidate as qubits for quantum computing without the need for cooling cryogenics.

Why it matters

Quantum supremacy

Quantum supremacy may include applications in the future such as 1) drug discovery: greatly speeding up the process and lowering the cost of developing treatments, 2) Material design: designing and optimizing new materials with desired properties, such as high strength or conductivity, 3) Financial modeling: analyze financial data and perform risk assessments quickly, potentially leading to more stable financial markets, 4) Climate modeling: perform more accurate simulations of the Earth's climate, which could help us better understand and mitigate the impacts of climate change. The importance of these possibilities is clear, and diamond-based qubits may bring quantum computing out of the lab and into our world.
