detailed list of edits

Typos on main page

• First line “an” Introduction:
• delete the 2nd “welcome to CUDA Quantum”
• Paragraph between 1st and 2nd code blocks rephrase “operation to affect a controlled-X” to be “operation which implements a controlled-X gate”
• Paragraph between 1st and 2nd code blocks: last sentence add a colon at the end.

Computing expectation values, in between code blocks

• Rephrase This angle is used as part of a single ry rotation. To “This angle become the argument of a single ry rotation”
• Computing expectation values in between code blocks, delete “we are interested in”
• Computing expectation values in between code blocks, rephrase “CUDA Quantum provides a generic function cudaq::observe, This function takes as input three terms. This first two terms are the parameterized kernel and the spin_op whose expectation value we wish to compute, respectively. The last term contains the runtime parameters at which we evaluate the parameterized kernel.
• Add a colon at the end of the last sentence

Multi-control Synthesis

• Delete the last sentence of the first paragraph
• Paragraph after 1st code block, spell out two.
• Add a colon at the end of the last sentence

Using Quantum Hardware Providers

• Add parenthesis listing the hardware providers so the reader can readily see what options are going to be presented (Quantinuum, IonQ)
• Missing “to” in “how to run kernels” before each code block

Typos in code blocks: Simulations with cuQuantum

• 3rd comment i.e. needs a comma
• Noisy simulation - depolarization
• 2nd comment: user-provided
• Rephrase depolarization channel comment (see python code edits)
• Replace “Meaning,” with “In other words,”

Noisy simulation - amplitude damping

• Rephrase amplitude damping channel comment (see python code edits)
• Replace “Meaning,” with “In other words,”

Noisy simulation - bit flip

• Rephrase bit flip channel comment (see python code edits)
• Replace “Meaning,” with “In other words,”
• Rephrase extra X gate similar to the python code edit

Noisy simulation -phase flip

• Rephrase phase flip channel comment (see python code edits)
• Replace “Meaning,” with “In other words,”
• Rephrase extra X gate similar to the python code edit
• Hyphenate phase-flip: “phase flip error on the gate”

Noisy simulation Kraus operators

• Last comment, edit: … case, but it is… in order to avoid interfering with…

Quantum Hardware Quantinuum

• Typo appears twice in the comments: E.g, needs to be in the previous sentence not capitalized and e.g., includes both periods and commas

IonQ Hardware Quantinuum

• Typo appears twice in the comments: E.g, needs to be in the previous sentence not capitalized and e.g., includes both periods and commas
