IBM’s quantum-resistant magnetic tape storage is not actually snake oil – gpgmail


Usually when someone in tech says the word “quantum,” I put my hands on my ears and sing until they go away. But while IBM’s “quantum computing safe tape drive” nearly drove me to song, when I thought about it, it actually made a lot of sense.

First of all, it’s a bit of a misleading lede. The tape is not resistant to quantum computing at all. The problem isn’t that qubits are going to escape their cryogenic prisons and go interfere with tape drives in the basement of some datacenter or HQ. The problem is what these quantum computers may be able to accomplish when they’re finally put to use.

Without going too deep down the quantum rabbit hole, it’s generally acknowledged that quantum computers and classical computers (like the one you’re using) are good at different things — to the point where in some cases, a problem that might take incalculable time on a traditional supercomputer could be done in a flash on quantum. Don’t ask me how — I said we’re not going down the hole!

One of the things quantum is potentially very good at is certain types of cryptography: It’s theorized that quantum computers could absolutely smash through many currently used encryption techniques. In the worst case scenario, that means that if someone got hold of a large cache of encrypted data that today would be useless without the key, a future adversary may be able to force the lock. Considering how many breaches there have been where the only reason your entire life wasn’t stolen was because it was encrypted, this is a serious threat.

IBM and others are thinking ahead. Quantum computing isn’t a threat right now, right? It isn’t being seriously used by anyone, let alone hackers. But what if you buy a tape drive for long-term data storage today, and then a decade from now a hack hits and everything is exposed because it was using “industry standard” encryption?

To prevent that from happening, IBM is migrating its tape storage over to encryption algorithms that are resistant to state of the art quantum decryption techniques — specifically lattice cryptography (another rabbit hole — go ahead). Because these devices are meant to be used for decades if possible, during which time the entire computing landscape can change. It will be hard to predict exactly what quantum methods will emerge in the future, but at the very least you can try not to be among the low-hanging fruit favored by hackers.

The tape itself is just regular tape. In fact, the whole system is pretty much the same as you’d have bought a week ago. All the changes are in the firmware, meaning earlier drives can be retrofitted with this quantum-resistant tech.

Quantum computing may not be relevant to many applications today, but next year who knows? And in ten years, it might be commonplace. So it behooves companies like IBM, which plan to be part of the enterprise world for decades to come, to plan for it today.

Why now is the time to get ready for quantum computing – gpgmail


For the longest time, even while scientists were working to make it a reality, quantum computing seemed like science fiction. It’s hard enough to make any sense out of quantum physics to begin with, let alone the practical applications of this less than intuitive theory. But we’ve now arrived at a point where companies like D-Wave, Rigetti, IBM and others actually produce real quantum computers.

They are still in their infancy and nowhere near as powerful as necessary to compute anything but very basic programs, simply because they can’t run long enough before the quantum states decohere, but virtually all experts say that these are solvable problems and that now is the time to prepare for the advent of quantum computing. Indeed, Gartner just launched a Quantum Volume metric, based on IBM’s research, that looks to help CIOs prepare for the impact of quantum computing.

To discuss the state of the industry and why now is the time to get ready, I sat down with IBM’s Jay Gambetta, who will also join us for a panel on Quantum Computing at our TC Sessions: Enterprise event in San Francisco on September 5, together with Microsoft’s Krysta Svore and Intel’s Jim Clark.

Frontier technologies are moving closer to the center of venture investment – gpgmail


As the technologies that were once considered science fiction become the purview of science, the venture capital firms that were once investing at the industry’s fringes are now finding themselves at the heart of the technology industry.

Investing in the commercialization of technologies like genetic engineering, quantum computing, digital avatars, augmented reality, new human-computer interfaces, machine learning, autonomous vehicles, robots, and space travel that were once considered “frontier” investments are now front-and-center priorities for many venture capital firms and the limited partners that back them.

Earlier this month, Lux Capital raised $1.1 billion across two funds that invest in just these kinds of companies. “[Limited partners] are now more interested in frontier tech than ever before,” said Bilal Zuberi, a partner with the firm.

He sees a few factors encouraging limited partners (the investors who provide financing for venture capital funds) to invest in the firms that are financing companies developing technologies that were once considered outside of the mainstream.
