Despite the naysayers, the hype around quantum computers is all real, and it’s also justified.
In order to fully realize the promise of quantum computing, it will still take a few years of scientific breakthroughs and intensive research. It still remains to be seen whether quantum computers will live up to the hype, but all hints point to that direction.
Now, there’s mathematical proof that these are real calculations that quantum computers will definitely be able to perform faster than any traditional system.
Quantum computers have a very limited number of qubits today and also short coherence time.
Researchers are really interested in seeing what they can do with the available tech of these machines. Due to the short coherence time, they can become chaotic and useless, and this means that you can only perform a small number of operations on them.
Quantum computers vs. traditional systems
TechCrunch reported that Science today published a paper (“Quantum advantage with shallow circuits”) by Sergey Bravyi of IBM Research, David Gosset of the University of Waterloo’s Institute for Quantum Computing and Robert König of the Institute for Advanced Study and Zentrum Mathematik, Technische Universität München.
In the paper, researchers prove that a quantum computer with a fixed circuit depth can outperform a classical computer that’s tackling the same issue because the circuit depth can stay constant in the first case.
The main question asked by researchers was if constant-depth quantum circuits can solve a computational problem that classical circuits cannot.
The problem the researchers decided to look at is a variation on the well-known Bernstein-Vazirani problem.
What researchers basically did was to show that even a shallow quantum computer can easily outperform a classical computer in solving this problem.
The result of the study definitely shows that it’s worth exploring quantum algorithms. More research and tests are required.
