A method and systems for taking downhole measurements. The method may include selecting a pulsing scheme for taking one or more measurements using a pulsed neutron logging tool, selecting a neutron burst width for the pulsing scheme based at least in part on a neutron tube utilized by the pulsed neutron logging tool to form at least in part a neutron burst train, and selecting a decay window in which the one or more measurements are performed by the pulsed neutron logging tool. The method may further include selecting a starting time for a late gate in which the one or measurements are taken, disposing the pulsed neutron logging tool into a borehole, performing the neutron burst train with the pulsed neutron logging tool, and performing the one or more measurements with the pulsed neutron logging tool during the late gate.

A technique for dual-comb high-resolution distributed sensing that employs a “gating” feature to the probe comb in the time-domain. Operationally, probe comb signals are gated as blocks and sent into a optical fiber with adjusted time intervals. In a signal processing stage, the block signals are merged as a complete analysis window such that every spatial resolution can be reconstructed. By sliding the window, the entire optical fiber can advantageously be monitored. Our technique advantageously breaks a sensing distance bottleneck found in conventional, dual-comb distributed fiber sensing, thereby providing high-spatial resolution sensing over a long distance.

A quantum key distribution system may include a transceiver including a state randomizer to impart a random state transformation to one or more qubits of a generated faint pulse and a quantum bit encoder to reflect the faint pulse back to the transceiver with one or more encoded bits. The transceiver may receive a return pulse through the communication channel, where the state randomizer reverses the random state transformation. The transceiver may include a set of two detectors to measure the return pulse at time-gated timeslots associated with possible paths of the return pulse. Reception of the faint pulse from the quantum bit encoder as the return pulse triggers a detector in one or more known time-gated timeslots determined based on the random state transformation, while reception of a faked-state pulse results in a non-zero probability of triggering of a detector in a different time-gated timeslot.
