Happy Earth Day to everyone! This day should remind everyone that we all need to do our part in reducing our dependence on fossil fuels to help overturn climate change. Whether it be getting an electric car or walking to school, everything helps. I am trying to play my part through QuantumFusion, pursuing the creation of the perfect synergy between a quantum computer and a fusion reactor in order to completely remove fossil fuels from our lifestyle. It’s not just me though; millions of people are committed to ending the reign of fossils and the researchers at Princeton are doing just that by giving quantum computers the assets to efficiently control fusion reactors.

The Department of Physics at Princeton University has made a major breakthrough that will revolutionize the practicality and efficiency of quantum computers. A group led by Jason Petta has just made a silicon qubit with a fidelity level, the distance between two quantum states, of just over 99.8%. Compare that to the average two-qubit raw fidelity being just 97.5%, and we see an incredible advancement. The higher the fidelity percentage, the better for quantum computers.

How do silicon qubits prove beneficial to quantum computers? Well, unlike the commonly used superconducting qubits that are unreliable and very big, the silicon qubits from Petta’s team are small and reliable. Silicon qubits are 3000 times smaller than the traditional superconducting qubit and this means a lot because limitations in scalability mean that the number of superconducting qubits can not be heavily increased; with tiny silicon qubits, we can pack more qubits into smaller hardware and end up with more accurate quantum computers.

So where does this play into QuantumFusion? We need the best quantum computers to make sure that fusion reactors are making us green energy as efficiently and safely as possible. Silicon qubits are a big step in that direction and they prove that the quantum revolution is coming rapidly.

Young quantum researchers are taking theoretical ideas and turning them into reality. After learning quantum physics, these researchers are changing the world by contributing to the quantum field in ways we could never imagine. In the article linked below, Akel Hashim, a postgraduate student in his 20s, is working towards reducing the noise created by quantum computers from coherent errors. Him and countless other young researchers are the future of this field. They dedicate their lives to bettering the world through their work with quantum computers. Whether it be reducing noise like Hashim, or coding quantum, algorithm’s, these people are making a change that contributes to our future and the future of every single generation to come.
