Abstract: The subject matter described herein provides techniques to ensure that queries of a distributed database observe a consistent read of the database without locking or logging. In this regard, next-write timestamps uniquely identify a set of write transactions whose updates can be observed by reads. By publishing the next-write timestamps from within an extendable time lease and tracking a “safe timestamp,” the database queries can be executed without logging read operations or blocking future write transactions, and clients issuing the queries at the “safe timestamp” observe a consistent view of the database as it exists on or before that timestamp. Aspects of this disclosure also provide for extensions, done cheaply and without the need for logging, to the range of timestamps at which read transactions can be executed.

Abstract: Methods, systems and apparatus for performing quantum state preparation. In one aspect, a method includes the actions of defining a target quantum state of a quantum system, wherein time evolution of the quantum system is governed by a target Hamiltonian, and defining a total Hamiltonian that interpolates between an initial Hamiltonian and the target Hamiltonian, wherein the total Hamiltonian is equal to the initial Hamiltonian at an initial time and is equal to the target Hamiltonian at a final time; approximating the time evolution of the total Hamiltonian using a truncated linear combination of unitary simulations to generate a truncated time evolution operator; evolving a ground state of the initial Hamiltonian according to the truncated time evolution operator for a truncated number of time steps to generate an intermediate state; and variationally adjusting the intermediate state to determine a wavefunction that approximates the target quantum state of the quantum system.

Abstract: This document describes techniques and systems that enable input methods for mobile devices. A radar field enables an electronic device to accurately determine that a part of a user is within a gesture zone around the device. Further, the device can determine whether an application configured to receive input through radar-based gestures (radar gestures) is operating on the device. Using these techniques, the device can present a feedback indicator on a display when the user's hand is within a gesture zone around the device. The feedback indicator alerts the user that the user's hand is close enough to the device to make specific radar gestures. This allows the device to provide the user with feedback, which can educate the user about the device's capabilities and allow the user to take advantage of additional functionality and features provided by the availability of the radar gestures.

Abstract: This document describes techniques directed to a scalable gesture sensor for wearable and soft electronic devices. The scalable gesture sensor is integrated into an object such as a wearable garment or a large-surface embedded system to provide a touch-sensitive surface for the object. The sensor includes a repeated localized crossover pattern formed by the same few sensor lines, resulting in the same two conductive lines having multiple crossover points across the touch-sensitive surface. The repeated crossover pattern enables detection of the occurrence and relative direction of a swipe gesture based at least on a repeated sequence of capacitance changes over a set of conductive lines in the repeated crossover pattern. Also, the scalable gesture sensor is computationally simple, uses low power, and is uniquely scalable to cover a large area with few electrodes.
