<p>A team of Chinese researchers have claimed a breakthrough to solve vulnerabilities of mainstream encryption mechanisms. They have claimed that their new, quantum code-breaking algorithm could reduce the scale of a practical quantum computer. The claim has been met with doubts from researchers in the United States.&nbsp;</p>

<p>The team, led by Professor Long Guilu of Tsinghua University, claimed in a yet-to-be-published paper that its new algorithm could reduce the scale of a practical quantum computer to 372 qubits, reported South China Morning Post.&nbsp;</p>
