Resumen de Quantum bank cheques may be forgery proof
It's old meets new. Quantum computers could create cheques that are nearly impossible to forge. Quantum computers store data using qubits which. unlike ones and zeros in classical computing, can exist in two states at once. It's impossible to observe a qubit in this superposition--it collapses into either a one or zero as soon as people measure it. Now Prasanta Panigrahi at the Indian Institute of Science, Education and Research in Kolkata has shown that by harnessing this quality, it is possible to make a quantum cheque that can't be spied on, and so can't be copied.
