Google and NASA have a lot in common, really. Both companies have made marks for themselves by defying logic, and in some ways, making the (seemingly) impossible... possible. Of course, Google has done most of its work on Planet Earth, while NASA has a thing for the outer reaches of space, but that's not stopping the two from working together. Google has just produced and published a video outlining the Quantum Artificial Intelligence Lab -- a facility built for the advancement of quantum computing. The lab is in its earliest days at the moment, but the potential here is huge. The video does a... Read more...
If you're reading this site, chances are you have heard of Moore's Law. You may have even heard of the law of diminishing returns. Or perhaps you've heard that fast is never fast enough, and big is never big enough. But have you heard of quantum computing? Most people hear that phrase and simply think of some science fiction movie that they have seen in the past. But outside of Hollywood fantasies, it rarely has any real meaning for the average consumer. That's mostly because quantum computing is still a pipe dream in real life, and even after decades of using silicon microchips to power our computers,... Read more...
Over the past couple of weeks, a company names D-Wave Systems made some news after announcing that they had developed what was supposedly the world's first commercial quantum computer.  And now D-Wave's claims have come under fire because they've failed to submit their findings for peer review. This story on CNN Tech discusses some of the finer details of the situation. "Quantum computing is such an elusive goal that even the company claiming to have the "world's first commercial quantum computer" acknowledged it isn't entirely sure the machine is performing true quantum calculations....

We've all heard of bits and bytes.  Ever hear of a qubit?  So it goes like this.  Bits, as we traditionally know them, are either in a 1 or 0 state.  Right, well, a qubit exists in a quantum state. So for example, it can be either 1 or 0 or both or somewhere in between.  This is the crux of quantum computing.  Sufficiently confused?  What if we told you a quantum computer or a system built with a quantum computing 16 qubit engine could carry out 64,000 calculations simultaneously in parallel universes?  Oh and a machine built with a hundreds of qubits...

I know you slept through quantum physics class. Your snoring woke me up. Luckily, Someone at Magiq Technologies, among other people, was sitting up straight and taking notes. And they think they can make the next generation of data encryption essentially impregnable by using those pesky photons from page 234 in the textbook we didn't read either: Magic combines a computer, a finely tuned laser, a photon detector, and a fiber-optic line. The laser inside the Magiq QPN box is adjusted to produce single photons, which are then sent over the fiber-optic... Read more...
DailyTech also has managed to uncover news regarding NVIDIA's upcoming Quantum Physics Engine. Slated to be released alongside the G80 GPU, NVIDIA will be announcing a new dedicated layer on the GPU which will be reserved for physics processing and be referenced as the "Quantum Physics Engine". Essentially, this new engine will allocate spare shaders towards physics processing. Obviously, the engine will scale well with SLI as there is a much larger pool of shaders though documents suggest that NVIDIA's physics processing can be done while using a single card as well. Given... Read more...
Quantum's Fireball CR EIDE Hard Drive ATA/66... Hot Hardware or Hype? A close look at a new ATA/66 Hard Drive from Quantum   Hard Drive technologies seem to leap frog themselves faster than any other techonolgy in the PC Hardware Arena. What is leading edge technology today will be "old hat" in a matter of months when the next level of performance or density is surpassed and brought to the marketplace. It seems as if 6 month design cycles are common place for drive makers. One of the main bottlenecks in traditional drive systems is the bus interface. SCSI has its advantages over... Read more...
  Quantum's Atlas 10K II Ultra160 SCSI Drive Taking advantage of all that bandwidth 8/27/00 - By  Dave "Davo" Altavilla Interface Speed, Spindle Speed, Access Times and Data Buffers, these are the major components driving the performance levels of any given Hard Drive technology.  Not long ago we brought you a full detailed review of the latest technology in SCSI Interfaces, Ultra160 and the Quantum AtlasV Ultra160 SCSI Drive.   The months have rolled on and so has the product development cycle for Quantum. In addition to this new found interface speed, Quantum... Read more...
  Quantum's Fireball Plus AS 40 Mainstream ATA100 performance @ 7200 RPM 3/5/01 - By  Dave Altavilla The first two Quantum drives we reviewed here at Hot Hardware, were very high end products with SCSI interfaces and targeted at the Server/Professional market.  Today we are going to look at one from Quantum's "Desktop" offering.  This drive is still targeted at the high end of the segment but with an ATA100 interface, it will most likely find its way to a system the likes of which are configured by many of you loyal Hot Hardware readers. As we all know, both spindle... Read more...
  Quantum's Atlas V Ultra160 SCSI Hard Drive SCSI One-Ups EIDE Again! 3/17/00 - By, Dave "Davo" Altavilla We've said this before and we'll say it again, your hard drive is one of the slowest parts of your computer.  Or is it?  Let's take a look at today's computer technology and the speed ratings for various types of components.  Let's see, your main system memory is rated in Nanoseconds.  Your Processor's clock frequency is rated in MHz  Your Graphics card is also measured in MHz for the processor and Nanoseconds for the memory.  Then there is the Hard...
