A team of American and Russian researchers at Harvard has created the world’s most advanced quantum computer. This 51 qubit quantum computer has been created using a technique called “cold atom.” The researchers, who’ve used the computer to solve many physics problems, are looking to test the computer with the Shor’s algorithm.

Most of you would be knowing about the basic working of the quantum computers, which allows the data to operate on quantum bits or qubits. As the number of qubits increases, the power of a quantum computer grows in an exponential manner.

Now, a team of Russian and American researchers at Harvard have created the world’s first 51 qubit quantum computer. In theory, a quantum machine with 50 working qubits is more powerful than the world’s most powerful computer.

Mikhail Lunkin, a Harvard professor and co-founder of Russian Quantum Center, said that the new machine has allowed his group to become the leader in the ongoing race to replace traditional Silicon-based chips, reported Sputnik News.

In the recent past, many tech giants and scientists have been working on creating an adiabatic (closer to digital approach) machine, which is one of the two approaches to create quantum systems–the other one is classical (closer to analog approach). Before this, the team of John Martinis, from Google, was creating a 22 qubit machine using the superconducting circuits.

On the other hand, Lukin’s team has used an exotic “cold atom” technology, which needs to keep a set of atoms inside special laser cells and cooling them at very low temperature.

Notably, Lupin’s team has already solved some physics problems that are too complicated to be solved by conventional computers. In future, the team plans to continue experimenting. A paper with the results of the work on 51 qubit quantum computer has been accepted for publication in a peer-reviewed journal.
