[1] Schrödinger Equation :
- The Schrödinger Equation Is A Fundamental Equation In
Quantum Mechanics That Describes The Behavior Of Quantum
Systems.
- It Is Named After The Austrian Physicist Erwin Schrödinger,
Who Formulated It In 1925.
- iħ ∂ψ/∂t = -ħ²/2m ∇²ψ + Vψ
- ψ (Psi): This Symbol Represents The Wave Function Of The
Quantum System.
- t: This Represents
Time.
- i: This Is The
Imaginary Unit (√(-1)).
- ħ (h-bar): This Is
The Reduced Planck's Constant
- ∂ψ/∂t: This Term Represents The Partial Derivative Of The
Wave Function With Respect To Time.
- ∇²ψ: This Term Represents The Laplacian Operator Applied To
The
Wave Function.
- m: This Represents
The Mass Of The Quantum System.
- V: This Represents The Potential Energy Of The Quantum
System.
- It Describes How The Wave Function Evolves In Time And
Provides The Basis For Understanding The Behavior And
Properties Of Quantum Systems.
[2] Schrödinger's Cat :
- Schrödinger's Cat Is A Thought Experiment Devised By
Austrian Physicist Erwin Schrödinger In
1935.
- It Is A Hypothetical Scenario Used To Illustrate Certain
Peculiarities Of Quantum
Mechanics.
- In The Experiment, Schrödinger Imagined A Sealed Box
Containing A Cat, A Vial Of Poison, And A Radioactive
Substance.
- The Radioactive Substance Has A 50% Chance Of Decaying
Within A Certain Time Period.
- If It Decays, It Triggers A Mechanism That Breaks The Vial Of
Poison And Leads To The Death Of The Cat. If It Doesn't Decay,
The Cat Remains Alive.
- The Thought Experiment Raises Questions About The Nature
Of Observation And Measurement In
Quantum Mechanics.
- When The Box Is Opened And The System Is Observed, The
Superposition Collapses, And The Cat Is Found To Be Either
Alive Or Dead.
- The Act Of Observation Causes The Wave Function To
"Collapse" Into A Definite
State.
- Schrödinger's Cat Experiment Highlights The Concept Of
Superposition And The Role Of Observation Or Measurement In
Quantum Mechanics.
[3] Schrödinger Picture :
- The "Schrödinger Picture" Refers To A Specific Formulation Or
Framework Within Quantum
Mechanics
- State Description: In The Schrödinger Picture, The State Of A
Quantum System Is Described By A State Vector Or Wave
Function (Ψ).The Wave Function Contains All The Information
About The System's Quantum State, Including Its Probabilities
And Amplitudes.
- Time Evolution: In The Schrödinger Picture, The Wave
Function Evolves Over Time According To The Schrödinger
Equation:
iħ
∂Ψ/∂T = Hψ
- The Schrödinger Picture Provides A Convenient Framework For
Describing The Time Evolution Of Quantum Systems And
Calculating Probabilities And Expectation Values.
- The Schrödinger Picture Is Widely Used In Quantum
Mechanics For Various Calculations And Theoretical
Descriptions Of Quantum Systems.
[4] Quantum Entanglement :
- Quantum Entanglement Is A Fundamental Concept In Quantum
Mechanics That Describes A Strong Correlation Between Two Or
More Particles, Even When They Are Physically
Separated.
- Superposition: Entanglement Often Arises Through The
Process Of Superposition, Where Quantum Particles Can Exist
In Multiple States Simultaneously. When Entangled Particles
Are In A Superposition,Their States Are Entangled As Well,
Resulting In Correlated Outcomes Upon Measurement.
- Quantum Entanglement Is Not Just A Theoretical Concept; It
Has Practical Applications. For Example, Entanglement Is
Crucial In Quantum Computing, Quantum Cryptography,
And Quantum Communication Protocols Like Quantum
Teleportation And Quantum Key
Distribution.
- It Plays A Crucial Role In Various Quantum Technologies And
Continues To Be An Active Area Of Research, Both For Its
Foundational Implications And Practical Applications.
[5] Quantum Superposition :
- Quantum Superposition Is A Fundamental Principle In
Quantum Mechanics That Allows Quantum Particles To Exist In
Multiple States Simultaneously.
- In Quantum Mechanics, Particles Can Exist In A Superposition
Of Multiple States, Where They Simultaneously Possess
Different Values Of A Particular Observable.
- Quantum Superposition Is Essential For Quantum Computing.
It Allows Quantum Bits (Qubits) To Exist In A Superposition Of
Both 0 And 1, Enabling Parallel Processing And The Potential
For Exponential Computational Power.
- It Plays A Crucial Role In Many Quantum Phenomena,
Experiments, And Technologies, And Challenges Our Classical
Intuitions About The Nature Of Reality.
