An international research group has for the first time demonstrated a quantum algorithm that performs a true calculation, without needing to know the answer before the start. The team's 'phase estimation algorithm', they say, is a central quantum algorithm which achieves an exponential speedup over all classical algorithms. It's a key sub-routine of many other important quantum algorithms, such as Shor's factoring algorithm and quantum simulations. "Before our experiment, there had been several demonstrations of quantum algorithms, however, none of them implemented the quantum algorithm without knowing the answer in advance. This is because in the previous demonstrations the quantum circuits were simplified to make it more experimentally feasible," says the University of Bristol's Dr Xiao-Qi Zhou, who led the project.

"Unlike previous demonstrations, we built a full quantum circuit to implement the phase estimation algorithm without any simplification. An Unexpected Ass Kicking.

BYTE, the most venerated tech media source of all time, is back! Authoritative, trusted and deeply technical, BYTE set the bar for tech coverage for decades. And I'm thrilled and so pleased to announce its return today, right in the middle of summer 2011. It's been too long! Originally launched in 1975, BYTE ushered in the personal computer revolution. Since BYTE closed down in 1998, there has been an aching chasm in tech journalism.

BYTE is here to focus on the technology you care most about. BYTE pulls no punches -- we'll dig deep to make sure you know exactly what you need to know to get the most out of your tech, to find out what's worth buying and what to avoid at all cost. I want to give a special thanks original BYTE folk who join us on its return.

To top it off, we have as our senior technologist Jerry Pournelle, whose Computing from Chaos Manor column was the first thing so many readers turned to in the decade. BYTE is back. Who is teamBYTE? Sam Abuelsamid. The Red Ferret Journal - Gadgets, freeware, cool sites, tech news and trivia.
