More believers; loving it!

As we continue to conduct more of our transactions online, consumers, companies and governments put their faith in encryption to protect their private and sensitive data. Once quantum computing becomes a reality, our current encryption methods will quickly become obsolete as quantum computers will be able to easily crack them.

With companies and governments investing heavily in quantum computing, it seems that a fully functioning quantum computer will become a reality in the not too distant future. A machine like that would have no problem cracking the encryption methods used across the Internet today.

Quantum computers will make today’s internet insecure. Therefore, we should consider replacing the current infrastructure now according to Dr. Vadim Makarov. He heads the Quantum Hacking Lab at the Institute for Quantum Computing at the University of Waterloo in Canada.

What’s next? Nanocavities in a diamond for small devices.

Researchers have developed a new type of light-enhancing optical cavity that is only 200 nanometers tall and 100 nanometers across. Their new nanoscale system represents a step toward brighter single-photon sources, which could help propel quantum-based encryption techniques under development.

Quantum encryption techniques, which are seen as likely to be central to future data encryption methods, use individual photons as an extremely secure way to encode data. A limitation of these techniques has been the ability to emit photons at high rates. “One of the most important figures of merit for single-photon sources is brightness — or collected photons per second — because the brighter it is, the more data you can transmit securely with quantum encryption,” said Yousif Kelaita of Stanford University.

In the journal Optical Materials Express, from The Optical Society (OSA), Kelaita and his colleagues show that their new nanocavity significantly increased the emission brightness of quantum dots — nanometer-scale semiconductor particles that can emit single photons.

Russian Quantum Center (RQC) said that it is ready to collaborate with India and offer its quantum technology that will prevent hackers from breaking into bank accounts. RQC plans to offer ‘quantum cryptography’ that could propel India to the forefront of hack proof communication in sectors such as banking and national and homeland security.

“We are ready to work with Indian colleagues. It (the technology) can’t be bought from the United States as it deals with the government and security,” said Ruslan Yunusov, chief executive at RQC, in an interview.

Established by Russia’s largest global technology hub, Skolkovo in 2010, RQC conducts scientific research that could lead to a new class of technologies. These include developing ‘unbreakable cryptography’ for the banks and the government organisations. It also involves research in areas such as materials with superior properties and new systems for ultrasensitive imaging of the brain. The research is mostly funded by the government money.

Groupon grief – was it password reuse?

The Telegraph reports that crooks have hijacked a number of Groupon accounts and used them to purchase expensive items like games consoles, iPhones and holidays. Some victims have suffered thousands of pounds of losses.

Let’s say closer to 7yrs or less.

Whether quantum computing is 10 years away — or is already here — it promises to make current encryption methods obsolete, so enterprises need to start laying the groundwork for new encryption methods.

A quantum computer uses qubits instead of bits. A bit can be a zero or a one, but a qubit can be both simultaneously, which is weird and hard to program but once folks get it working, it has the potential to be significantly more powerful than any of today’s computers.

And it will make many of today’s public key algorithms obsolete, said Kevin Curran, IEEE senior member and a professor at the University of Ulster, where he heads up the Ambient Intelligence Research Group.

Researchers have developed a new type of light-enhancing optical cavity that is only 200 nanometers tall and 100 nanometers across. Their new nanoscale system represents a step toward brighter single-photon sources, which could help propel quantum-based encryption and a truly secure and future-proofed network.

Nice write up about why businesses need to worry about QC sooner v. later. Glad to see more spreading the word.

It’s coming sooner than you think.
