Metal Project 1A: Designing a simple two-qubit chip

[veenaiyuri]

Abstract

The designing of a simple two qubit chip using Qiskit Metal.

Description

Using Qiskit Metal, design a single plane, two-qubit chip using superconducting qubits, which are coupled together with a coplanar waveguide (CPW) bus resonator (capacitively), and with each qubit having a CPW readout resonator. The readout resonators should be capacitively coupled to transmission line(s) which connect to launcher pad(s) for wire bonds. All qcomponents should be selected from those available in the qlibrary.A simple model of the potential layout is shown below:

The project members are to determine the actual physical layout, with the below target parameters in mind. Try to land within +/-5% of targets.

Parameters	Target Value	Parameters	Target Value
Freq_Q1	5.5 GHz	Freq_readout_Q1	7.5 GHz
Freq_Q2	5.7 GHz	Freq_readout_Q2	7.7 GHz
Anharmonicity (Ec)	300 MHz	χ	400 kHz
		Q_ext	20,000
Freq_bus	6.6 GHz
g_bus	60 MHz

The project members can also decide on the chip size, though should consider issues such as, potential box/substrate modes, or cross talk between the different components on the chip. It can be assumed wirebonds are available to be added where desired.

• Qiskit Coach: @marcolincs, @grace-harper-ibm, @priti-ashvin-shah-ibm

Deliverable

• The design notebook.
• Documentation showing the successful simulation/analysis of the chip design meeting the desired parameters. Explanations on design choices should also be included where appropriate.
• A gds file of said design.
