Techniques for optimizing bitrates and resolutions during encoding
In one embodiment of the present invention, an encoding bitrate ladder selector tailors bitrate ladders to the complexity of source data. Upon receiving source data, a complexity analyzer configures an encoder to repeatedly encode the source data-setting a constant quantization parameter to a different value for each encode. The complexity analyzer processes the encoding results to determine an equation that relates a visual quality metric to an encoding bitrate. The bucketing unit solves this equation to estimate a bucketing bitrate at a predetermined value of the visual quality metric. Based on the bucketing bitrate, the bucketing unit assigns the source data to a complexity bucket having an associated, predetermined bitrate ladder. Advantageously, sagaciously selecting the bitrate ladder enables encoding that optimally reflects tradeoffs between quality and resources (e.g., storage and bandwidth) across a variety of source data types instead of a single, “typical” source data type.

Dynamic digital communication system control
Control of a digital communication system having a plurality of communication lines on which signals are transmitted and received is implemented using a variety of methods and systems. According to one embodiment of the present invention, a method is implemented where the signals are affected by interference during transmission and each of the communication lines has at least one transmitter and at least one receiver.

Magic state distillation with low space overhead and asymptotic input count
Disclosed herein are example embodiments of protocols to distill magic states for T-gates. Particular examples have low space overhead and use an asymptotically optimal number of input magic states to achieve a given target error. The space overhead, defined as the ratio between the physical qubits to the number of output magic states, is asymptotically constant, while both the number of input magic states used per output state and the T-gate depth of the circuit scale linearly in the logarithm of the target error. Unlike other distillation protocols, examples of the disclosed protocol achieve this performance without concatenation and the input magic states are injected at various steps in the circuit rather than all at the start of the circuit. Embodiments of the protocol can be modified to distill magic states for other gates at the third level of the Clifford hierarchy, with the same asymptotic performance. Embodiments of the protocol rely on the construction of weakly self-dual Calderbank-Shor-Steane codes (“CSS codes”) with many logical qubits and large distance, allowing one to implement control-Swaps on multiple qubits. This code is referred to herein as the “inner code”. The control-Swaps are then used to measure properties of the magic state and detect errors, using another code that is referred to as the “outer code”. Alternatively, one can use weakly-self dual CSS codes which implement controlled Hadamards for the inner code, reducing circuit depth. Several specific small examples of this protocol are disclosed herein.

Parallel pipeline logic circuit for generating CRC values utilizing lookup table
CRC generation circuitry includes a lookup-table storing N-bit CRC values for M one-hot data frames. N AND gates for each bit of a M-bit data frame receive that bit of the M-bit data frame and a different bit of a N-bit CRC value from the lookup-table corresponding to a position of the bit in the M-bit data frame. N exclusive-OR gates each receive output from one of the N AND gates for each bit of the M-bit data frame. The N exclusive-OR gates generate a final N-bit CRC value for the M-bit data frame. The CRC value is therefore generated with a purely combinational circuit, without clock cycle latency. Area consumption is small due to the small lookup-table, which itself permits use of any generator polynomial, and is independent of the width of the received data frame. This device can also generate a combined CRC for multiple frames.
