ANNOUNCEMENT OF SOFTWARE SPECIFICATION AND ALGORITHM FOR THE NKTg LAW OF VARIABLE INERTIA

© 2026 Nguyễn Khánh Tùng. All rights reserved.

I. GENERAL INFORMATION

• Software Name:

NKTg Variable Inertia Computing System (NKTg Dynamics Calculator).

• Author:

Nguyễn Khánh Tùng

• Programming Languages:

C++ (ISO/IEC 14882) and Assembly (x64).

II. THEORETICAL BASIS: NKTg LAW OF VARIABLE INERTIA

The software is implemented based on the principles of the NKTg Law:

• Fundamental Relationship:

Movement tendency depends on position (x), velocity (v), and mass (m). Formula: NKTg = f(x, v, m).

• Core Product Quantities:
  • Momentum (p): p = m * v
  • NKTg_1 Quantity: Product of position and momentum (NKTg_1 = x * p).
  • NKTg_2 Quantity: Product of the mass variation rate and momentum (NKTg_2 = (dm/dt) * p).
• Unit of Measurement:

NKTm (Unit of variable inertia).

III. DETAILED ALGORITHM DESCRIPTION

1. Data Processing Workflow

The algorithm performs movement tendency analysis through logical steps:

• Step 1:

Receive input parameters: position (x), velocity (v), mass (m), and mass change rate (dm/dt).

• Step 2:

Calculate linear momentum p = m * v.

• Step 3:

Calculate variable inertia values NKTg_1 and NKTg_2.

• Step 4:

Classify the tendency (Tendency) based on the sign of the value:

• NKTg_1 > 0: Moving away from stable state.
• NKTg_1 < 0: Moving toward stable state.
• NKTg_2 > 0: Mass variation supports movement.
• NKTg_2 < 0: Mass variation resists movement.

V. DEFINITION OF STABLE STATE

The stable state in this software is defined as a state where position (x), velocity (v), and mass (m) interact to maintain the movement structure, avoiding loss of control and preserving the original movement pattern of the object.

VI. QUANTUM EXPANSION: NKTg ALGORITHM ON QUANTUM COMPUTING PLATFORMS

1. Quantum Theoretical Basis

The quantum expansion preserves all core quantities of the NKTg Law:

• Momentum (p): p = m * v
• NKTg_1 Quantity: Product of position and momentum (NKTg_1 = x * p)
• NKTg_2 Quantity: Product of the mass variation rate and momentum (NKTg_2 = (dm/dt) * p)
• Unit of Measurement: NKTm (Unit of variable inertia)

Instead of calculating each combination (x, v, m, dm/dt) sequentially as in the classical model, the quantum model encodes the entire parameter space into a superposition state and exploits quantum parallelism for searching.

2. Quantum Problem Statement

• Input: Parameter space (x, v, m, dm/dt), each variable is discretized into N = 2^n value levels, encoded using n qubits. Total search space consists of M = N^4 = 2^{4n} combinations.
• Problem: Given a tendency condition f selected from the set:

Condition f	Tendency
NKTg_1 > 0	Moving away from stable state
NKTg_1 < 0	Moving toward stable state
NKTg_2 > 0	Mass variation supports movement
NKTg_2 < 0	Mass variation resists movement
NKTg_1 > 0 and NKTg_2 < 0	Combination of two conditions

Find all combinations (x, v, m, dm/dt) ∈ {1..N}^4 satisfying the chosen condition f.

• Output: The set of parameter combinations satisfying f, obtained after quantum measurement.

3. Quantum State Space

The entire parameter space is encoded into a 4n-qubit quantum register:

|q⟩ = |x⟩ ⊗ |v⟩ ⊗ |m⟩ ⊗ |dm/dt⟩

The initialization state is a uniform superposition via Hadamard gates:

|s⟩ = H^{⊗ 4n} |0⟩^{4n} = (1/√M) ∑ |x, v, m, dm/dt⟩

Each combination exists simultaneously with an initial probability amplitude of 1/√M.

4. Quantum Processing Algorithm

The algorithm performs NKTg tendency analysis through logical steps:

• Step 1: Receive and encode input parameters (x, v, m, dm/dt) into the 4n-qubit register. Apply Hadamard gates to create uniform superposition across all M = N^4 combinations.
• Step 2: Build an Oracle Ô̂ parameterized according to the chosen tendency condition f. The Oracle performs three reversible operations:
  • Compute: Calculate p = m * v, NKTg_1 = x * p, NKTg_2 = (dm/dt) * p onto the ancilla register.
  • Phase kickback: Flip the phase of states satisfying f.
  • Uncompute: Restore ancilla to |0⟩.

Ô̂ |x,v,m,dm/dt⟩ = -|x,v,m,dm/dt⟩ if f(x,v,m,dm/dt) = 1

Ô̂ |x,v,m,dm/dt⟩ = +|x,v,m,dm/dt⟩ if f(x,v,m,dm/dt) = 0

• Step 3: Apply the Diffusion operator — amplify the amplitudes of solution states and suppress non-satisfying states:

D̂ = 2|s⟩⟨ s| – I

• Step 4: Repeat Step 2 and Step 3 for T optimal rounds. With k being the number of solutions in space M:

T = ⌊(π/4) * √{M/k}⌋ iterations.

After T rounds, the probability of measuring the correct solution approaches 1.

• Step 5: Measure the 4n-qubit register — obtaining combination (x, v, m, dm/dt) satisfying condition f with high probability. Repeat O(k) times to collect all k solutions.

5. Comparison between Classical and Quantum Models

Criteria	Classical Model	Quantum Model
Search space	M = N^4 combinations	M = N^4 = 2^{4n} states
Processing method	Sequential per combination	Quantum parallel
Complexity	O(M) = O(N^4)	O(√M) = O(N^2)
Speedup	—	Quadratic compared to classical
Resources	Unlimited memory	4n + ancilla qubits
Search condition	One condition f per run	One condition f per run

6. Scientific Significance

The NKTg quantum model preserves the entire physical nature of the NKTg Law — the NKTg_1, NKTg_2 quantities and tendency classification criteria — while exploiting Grover’s Algorithm to reduce search complexity from O(M) = O(N^4) to O(√M) = O(N^2). The Oracle is designed to be parameterized, allowing flexible application to any tendency condition within the NKTg set. This is a natural expansion step from classical models to quantum computing, opening directions for application in complex physical system simulation and large-scale parameter optimization.
