Three punt pole shoes in varying states of wear. A setting pole or quant (quant pole) is a pole, handled by a crew member, to move boats, barges (in which case it is also called a barge pole) or punts by pushing the craft in the desired direction. The pole is used to push against the river or sea bed or, in some cases, the bank of the river.
¯ Parity measurement circuit Stabilizer measurements are parity measurements that measure the stabilizers of physical qubits. [ 5 ] For example, to measure the first stabilizer ( X Z Z X I {\displaystyle XZZXI} ), a parity measurement of X {\displaystyle X} of the first qubit, Z {\displaystyle Z} on the second, Z {\displaystyle Z} on the third ...
Printed circuit boards, during which components are graphically placed on the board and the wires drawn between them; Integrated circuits, during which a layout of a larger block of the circuit or the whole circuit is created from layouts of smaller sub-blocks; FPGAs, during which logic elements are placed and interconnected on the grid of the FPGA

Historically this could be literally a breadboard, a wooden board with components attached to it and joined up with wire. More recently the term is applied to a board of thin insulating material with holes at standard 0.1-inch pitch; components are pushed through the holes to anchor them, and point-to-point wired on the other side of the board.
A common form of in-circuit testing uses a bed-of-nails tester.This is a fixture that uses an array of spring-loaded pins known as "pogo pins". When a printed circuit board is aligned with and pressed down onto the bed-of-nails tester, the pins make electrical contact with locations on the circuit board, allowing them to be used as test points for in-circuit testing.
In building wiring, multiway switching is the interconnection of two or more electrical switches to control an electrical load from more than one location.A common application is in lighting, where it allows the control of lamps from multiple locations, for example in a hallway, stairwell, or large room.
Eight switches offer 256 (2 8) combinations, which is equivalent to one byte. A tri-state type DIP switch can be in one of three positions (+, 0, −) which allows more codes than a binary DIP switch. For example, 8 pole tri-state DIP switches offer 6,561 (3 8) combinations/codes compared to 8 pole binary switches' 256 (2 8) combinations/codes ...
