Quantum computing generally involves the use of quantum mechanical phenomena to perform computing and information processing functions. Quantum computing uses quantum physics to encode and process information, rather than relying on transistor-based binary digital technology. In other words, while classical computers can operate with bit values that are either 0 or 1, quantum computing devices can operate according to the laws of quantum physics and can use qubits (also called quantum bits) that can exhibit phenomena such as superposition, entanglement, or combinations thereof. The superposition principle of quantum physics allows a qubit to be in a state that simultaneously partially represents both the value "1" and the value "0". The entanglement principle of quantum physics allows qubits to be correlated. For example, the state of a first qubit may depend on the state of a second qubit, or vice versa, or a combination thereof. Therefore, quantum circuits, by using qubits, can encode and process information in ways that are quite different from transistor-based binary digital technology. In practice, quantum computing has the potential to solve problems that, due to computational complexity, cannot be solved on classical computers, or can only be solved relatively slowly. Quantum computing can operate on qubits using dedicated control units such as quantum circuits. A quantum circuit is a variation that can perform operations on qubits. For example, a quantum circuit as part of a quantum program can be implemented as one or more quantum gates, such as a series of quantum gates. A quantum gate can be implemented as one or more physical operations on a set of qubits, such as implementing a series of pulses. A pulse is a time-dependent tone (e.g., a wave or waveform) and can be applied to a qubit to change its state, analyze its state, or a combination thereof. Quantum programming may involve the process of assembling a set of instructions, which may be called a quantum program, that can be executed on a quantum computer. A quantum program may be associated with a set of quantum circuits. When a quantum program is executed, for example, one or more measurements may be calculated by a
