Sep 27, 2021 · Efficient decompositions of multi-qubit gates are essential in NISQ applications, where the number of gates or the circuit depth is limited. This paper presents efficient …

Jul 1, 2024 · In this paper, we introduce decompositions of the multiple controlled- 𝑍 (ccz and cccz) gates tailored to various qubit-coupling graphs. Specifically, we demonstrate that the ccz gate …

For the implementation of a certain quantum algorithm, I need to construct a multi-qubit (in this case, a three-qubit) controlled-Z gate from a set of elementary gates, as shown in the figure …

We provide a method for compiling approximate multicontrolled single qubit gates into quantum circuits. Without ancilla qubits, the total number of elementary gates to decompose an n-qubit …

In the computational basis, this gate flips the phase of the target qubit if the control qubits are in the ∣ 11 ∣11 state. Create new CCZ gate.

First, the CCZ gate can be synthesized from CN OT and T gates, shown in Fig. 3 (a). We observe that both CN OT and T gates are "almost classical gates" Definition II.2.

Efficient decompositions of multi-qubit gates are essential in NISQ applications, where the number of gates or the circuit depth is limited. This paper presents efficient decompositions of CCZ …

Sep 27, 2022 · Here, by virtue of the Rydberg blockade effect, we propose a scheme to rapidly implement a three-Rydberg-atom CCZ gate via a single Rydberg pulse, and successfully apply …
