High-Temperature Gibbs States Are Unentangled and Efficiently Preparable

high-temperature-gibbs-states-are-unentangled-and-efficiently-preparable

Abstract:We show that thermal states of local Hamiltonians are separable above a constant temperature. Specifically, for a local Hamiltonian $H$ on a graph with degree $mathfrak{d}$, its Gibbs state at inverse temperature $beta$, denoted by $rho =e^{-beta H}/ textrm{tr}(e^{-beta H})$, is a classical distribution over product states for all $beta < 1/(cmathfrak{d})$, where $c$ is […]

Interview with Signal President Meredith Whittaker

interview-with-signal-president-meredith-whittaker

ten years ago, WIRED published a news story about how two little-known, slightly ramshackle encryption apps called RedPhone and TextSecure were merging to form something called Signal. Since that July in 2014, Signal has transformed from a cypherpunk curiosity—created by an anarchist coder, run by a scrappy team working in a single room in San […]

The slow evaporation of the free/open source surplus

Free/open source has been on my mind lately – more than usual. (FOSS or OSS for short, the distinction matters, a lot, but for the purposes of this post the two are similar enough to lump together.) This was triggered by reading a couple of posts the other day: Tara Tarakiyee’s Is the Open Source […]

Atari is known for a lot of video game consoles over the years, none of which were as successful as their first, the Atari Video Computer System (known as the VCS and later the 2600). But their 2nd-most popular console was the Atari 7800, an odd system with an odder history. This post is a […]

File Copying Olympics: How File Size Impacts the Race for Performance Gold

file-copying-olympics:-how-file-size-impacts-the-race-for-performance-gold

I had the opportunity to evaluate the new U34 Bolt from Oyen, and I was only disappointed that this device doesn’t literally scream or burn a hole through the desk. While delivering a stunning 3.1GB/s of sustained throughput, it was completely silent and no warmer than a cup of coffee (120°F/49°C). As exciting as that […]
