Distant, yet urgent
Any organization which handles sensitive data should start preparing now for the arrival of quantum computing. The technology is unlikely to be ready for widespread use for quite a few more years – maybe even another couple of decades – but it has been known for some time that when it is ready, it will crack the encryption used by governments, armies, banks, and hospitals. Messages sent today will become insecure overnight.
A tough subject
Quantum computing is a tough subject to explain. As Niels Bohr liked to put it, “Anyone who is not shocked by quantum theory has not understood it." Richard Feynman helpfully added “I think I can safely say that nobody understands quantum mechanics."
In a nutshell, quantum computing employs the weird properties of quantum mechanics like superposition and entanglement. Classical computing uses binary digits, or bits, which are either on or off. Quantum computing, however, uses qubits, which can be both on and off at the same time, and this characteristic makes them far more computationally powerful.
Dr Ignacio Cirac
To understand quantum computing properly, one needs a deep expert who can explain it in lay terms, and someone like Dr Ignacio Cirac certainly fits the bill. Cirac is director of the Max Planck Institute of Quantum Optics in Germany and holds honorary and visiting professorships pretty much everywhere that serious work is done on quantum physics. He has done seminal work on the trapped ion approach to quantum computing and several other aspects of the field and has published almost 500 papers in prestigious journals. He is even spoken of as a possible Nobel Prize winner. Most recently, he hThe content herein is subject to copyright by The Yuan. All rights reserved.
