connection¶

Falcon binding for falconCore::physics::device_structures::Connection — a named, typed quantum-device terminal (gate or ohmic contact).

Installation¶

import "libs/falconCore/physics/deviceStructures/connection/connection.fal";

Overview¶

A Connection represents a single electrical contact on a quantum device. Each connection has a name (e.g. "P1", "B2") and a type drawn from one of five device-feature categories:

Type	Factory
Plunger gate	`Connection.NewPlungerGate(name)`
Barrier gate	`Connection.NewBarrierGate(name)`
Reservoir gate	`Connection.NewReservoirGate(name)`
Screening gate	`Connection.NewScreeningGate(name)`
Ohmic contact	`Connection.NewOhmic(name)`

Example¶

import "libs/falconCore/physics/deviceStructures/connection/connection.fal";

Connection p1 = Connection.NewPlungerGate("P1");
Connection b1 = Connection.NewBarrierGate("B1");
Connection s1 = Connection.NewOhmic("S1");

string name = p1.Name();          // "P1"
string type = p1.Type();          // "PlungerGate"
bool   isG  = p1.IsGate();        // true
bool   isO  = s1.IsOhmic();       // true
bool   same = p1.Equal(p1);       // true
bool   diff = p1.NotEqual(b1);    // true
