摘要： A probabilistic digitizer for extracting information from a Josephson comparator is disclosed. The digitizer uses statistical methods to aggregate over a set of comparator readouts, effectively increasing the sensitivity of the comparator even when an input signal falls within the comparator's gray zone. Among other uses, such a digitizer may be used to discriminate between states of a qubit.

摘要： A resistive switching device includes a first electrode and a transition metal oxide layer formed on the first electrode. An oxygen scavenging electrode is formed on the transition metal oxide wherein the oxygen scavenging electrode removes oxygen from the transition metal oxide layer to increase formation of oxygen vacancies in the transition metal oxide layer to enable a switching mode when a bias is applied between the first electrode and the oxygen scavenging electrode.

摘要： Embodiments include methods and systems of neuron leaky integrate and fire circuit (NLIFC). Aspects include: receiving an input current having both AC component and DC component at an input terminal of the NLIFC, extracting AC component of input current, generating a number of swing voltages at a swing node using extracted AC component of the input current, transferring charge from a pull-up node to a neuron membrane potential (NP) node through an integration diode and a pull-up diode to raise a voltage at NP node over an integration capacitor gradually and the voltage at NP node shows integration value of AC component of input current, implementing leaky decay function of the neuron leaky integrate and fire circuit, detecting a timing of neuron fire using an analog comparator, resetting a neuron membrane potential level for a refractory period after neuron fire, and generating fire output signal of the NLIFC.

摘要： A pulse generator and a method of fabricating a pulse generator are described. The pulse generator includes an input node to receive an input voltage, a first capacitor, and a second capacitor. The first capacitor is positioned between the input node and the second capacitor. An output node outputs an output voltage with a pulse shape, and the pulse generator also includes at least one switch between the input node and the second capacitor. The at least one switch controls the pulse shape of the output voltage.

摘要： Embodiments are related to improving the bandwidth of classical networks using quantum networks. Sender equipment transfers quantum bits over a quantum communications network to receiver equipment, the quantum bits being used to obtain entry values in a shared dictionary. The sender equipment determines a solution for an optimization problem using the entry values, where data to be transferred over a telecommunications network is expressed by the optimization problem. The sender equipment transfers the solution over the telecommunications network to the receiver equipment, where an equivalence of the data is transferred to the receiver equipment in response to the receiver equipment using the solution, the optimization problem, and the entry values to obtain the data.
