Abstract: Dynamic data quantization may be applied to minimize the power consumption of a system that implements a convolutional neural network (CNN). Under such a quantization scheme, a quantized representation of a 3×3 array of m-bit activation values may include 9 n-bit mantissa values and one exponent shared between the n-bit mantissa values (n<m); and a quantized representation of a 3×3 kernel with p-bit parameter values may include 9 q-bit mantissa values and one exponent shared between the q-bit mantissa values (q<p). Convolution of the kernel with the activation data may include computing a dot product of the 9 n-bit mantissa values with the 9 q-bit mantissa values, and summing the shared exponents. In a CNN with multiple kernels, multiple computing units (each corresponding to one of the kernels) may receive the quantized representation of the 3×3 array of m-bit activation values from the same quantization-alignment module.

Abstract: Aspects of the present disclosure describe techniques for controlling coherent crosstalk errors that occur in multi-channel acousto-optic modulators (AOMs) by applying cancellation tones to reduce or eliminate the crosstalk errors. For example, a method and systems are described that include applying a first radio frequency (RF) tone to generate a first acoustic wave in a first channel of the multi-channel AOM, wherein a portion of the first acoustic wave interacts with a second channel to cause a crosstalk effect, and applying a second RF tone to generate a second acoustic wave in the second channel, wherein the second acoustic wave reduces or eliminates the crosstalk effect caused by the portion of the first acoustic wave.

Abstract: A video game matchmaking and match authentication system is configured to interact with a third party game software and game server to supplement or replace that third party's matchmaking process. The system builds a player profile and unique player signature for each player based upon their performance within a game, and based upon the raw player inputs received from a game controller. The player signature indicates the player's skill within a particular game or game genre, and also provides a unique representation of the player's expected performance, skill, and raw inputs for future matches within that game or game genre. Matchmaking is player driven to provide a desired match experience, and player skill matching occurs based on the player signatures. Monitoring and authentication occurs during the match and is based on analysis of raw inputs and match events to identify irregularities that suggest intentional manipulation.

Abstract: The disclosure describes aspects of laser cavity repetition rate tuning and high-bandwidth stabilization of pulsed lasers. In one aspect, an output optical coupler is described that includes a cavity output coupler mirror, a piezoelectric actuator coupled to the cavity output coupler mirror, a locking assembly within which the cavity output coupler mirror and the piezoelectric actuator are positioned, and one or more components coupled to the locking assembly. The components are configured to provide multiple positional degrees of freedom for tuning a frequency comb spectrum of the pulsed laser (e.g., tuning a repetition rate) by adjusting at least one position of the locking assembly with the cavity output coupler mirror. A method of adjusting an output optical coupler in a pulsed laser is also described. These techniques may be used in different applications, including quantum information processing.

Abstract: The disclosure describes various aspects of acousto-optic modulator (AOM) configurations for quantum processing. A method is described including generating, by a first AOM from a laser beam, first and second diffracted laser beams at different angles based on first and second radio frequency (RF) tones. An optical component focuses the diffracted laser beams onto a second AOM, which generates third and fourth diffracted laser beams based on the first RF tone and a third RF tone and the second RF tone and a fourth RF tone respectively, wherein the third and fourth diffracted laser beams are substantially parallel when incident on a respective ion in a chain of ions in a trap. Quantum information in the ion is controlled to perform quantum processing based on the third and fourth diffracted laser beams. Another method is described including generating, by an AOM, a small polarization rotation of an undiffracted laser beam.
