QuBlox v2.0

QuBlox v2.0

Changes

• Optimized Statevector Calculations
• Added direct amplitude modification
• Added throttling to prevent script exhaustion and frame drops
• Raised qubit limit to >20 qubits
• For qubit amounts under 15, 5000+ gates can be done under a minute

Benchmarks

Example:

• 7-qubit GHZ state
• 500,000 measurements
• ~747 milliseconds

Example:

• 5-qubit GHZ state
• 1,000 measurements
• ~1.1 milliseconds

Example:

• 26-qubit GHZ state (max possible qubits for Roblox)
• 1,000 measurements
• ~102 seconds

QuBlox v2.0-preview5

Added DirectGate:SWAP()
Added DirectGate:CZ()

Added Optimizations to full hadamard states
Added Optimizations to :results
Added --!native to QuBlox, BufferMatrix, DirectGate and Matrices

Fixed throttling issues causing 10000x performance loss

Slowly making BufferMatrix obsolete

Benchmarks:
Example:
20 qubit - 600 gates:
100k shots
~31 seconds

QuBlox v2.0-preview4

Added BufferMatrix.GetStateOpt()
Added BufferMatrix.SetStateOpt()
Added BufferMatrix.SwapState()

Added Matrices:CloneMatrix()

Optimized DirectGate:CNOT()
Optimized DirectGate:CCNOT()

Removed Matrices:ExpandGate()
Removed Matrices:Identity()
Removed Matrices:Tensor()
Removed Matrices:Column()

Removed QuBlox:CloneMatrix()

mid-circuit will not be added to v2
Classical bits are obsolete until later previews

Benchmarks:
Example:
26 qubit GHZ state:
1k shots
~104 seconds

Example:
23 qubit GHZ state:
1k shots
~9 seconds

Additional information

QuBlox v2.0-preview3

Added DirectGate module
Added DirectGate:CNOT()
Added DirectGate:CCNOT()

Removed Vectors module
Removed QuBlox.ReturnI()

Updated Github README.md
Expanded API documentation

Benchmark comparison:

v1
8 qubit GHZ state:
10k shots
Script exhaustion timeout

v2.0-preview3
8 qubit GHZ state:
10k shots
~1 second

QuBlox v2.0-preview2

Removed QuBlox:GetMultiOperations()
Removed QuBlox:GetSingleOperations()
Removed findMultiGates()
Removed findSingleGates()
Removed removeDuplicateGates()
Removed QuBlox:GetCircuitMatrix
Removed QuBlox:GetTensorMatrix
Removed QuBlox:GetMultiMatrix

Added QuBlox:applyMultiQubit()
Added getIndex()
Added a general support algorithm for direct amplitude modification

Refactored QuBlox:UpdateStateVector()

Benchmarks:
7 qubit GHZ state
500k shots
~0.89s

Updating the state vector now takes 1.3ms for the
7 qubit GHZ state.

New bottleneck:
Results comes up with 0.89s of time for the 7 qubit GHZ state, this is a problem for a high-shot lower qubit circuits

Can now support 15+ qubits

QuBlox v2.0-preview1

Removed QuBlox:GetTensorMatrix()
Renamed QuBlox:GetTensorOperations() to QuBlox:GetSingleOperations()
Added QuBlox:UpdateSingularState()

Starting major architectural changes and optimizations

QuBlox v1.1

Updated Statevector creation
Replaced Circuit.qubits with empty table objects for now
Limit is now 9 qubits due to matrix multiplication optimizations
Removed Conjugate Transpose
Matrix multiplication and gate expansion are soon to be obsolete
Vector.Qubit(0 or 1) now returns {}
