The 10-part Channel 4 and Sony Pictures Television series, based on Dick's short stories, will star Breaking Bad's Bryan Cranston.
Other writers on the project include Matthew Graham (Doctor Who) and 50 Shades screenwriter Kelly Marcel.
Filming is expected to begin early next year.
Fear and Loathing in Las Vegas writer Tony Grisoni is also one of the scriptwriters on board.
The new writers were revealed at a dinner ahead of the Edinburgh International Television Festival.
Each episode of Electric Dreams will be a standalone piece, adapted by a team of authors which also includes Masters of Sex's Michael Dinner and Outlander's Ronald D Moore.
Dick, who died in 1982 at the age of 53, had 44 novels published. His first was Solar Lottery in 1955.
He is best known for works including The Man in the High Castle and Do Androids Dream of Electric Sheep? - the basis of 1982 film Blade Runner.
Other films based on Dick's books include Total Recall and Minority Report. He also wrote more than 100 short stories.
Harry Potter and the Cursed Child, the West End stage play written by Thorne, is set 19 years after the seventh and final book in the series by JK Rowling.
Presented in two parts and running to more than five hours, it shows the main characters from the books as adults in their mid-30s as their own children head off to Hogwarts.
Demand for tickets for the two-part show has been huge. The show is sold out, although there is an online lottery every Friday in which 40 tickets are released for every performance the following week.
Thorne's other TV credits include two Bafta-winning series, This is England and The Fades.

Ex-Bank of England deputy governor Sir Charlie Bean is reviewing how official statistics are collected, and his initial findings are due on Wednesday.
The PCS union said it would "strongly oppose" transferring work or jobs from Newport, where 2,000 staff are based
The ONS said it was not "helpful" to speculate on the report's findings.
The ONS transferred hundreds of jobs from London to Newport in the late 2000s.
PCS union representative Gez Kirby said: "There's some anxiety obviously."
He told the BBC's Sunday Politics Wales programme: "We believe we produce high quality economic statistics and we don't want to see any of our work or our jobs move out of Newport."
Mr Kirby added: "We welcome any recommendation coming from the Bean Review, to increase the economic expertise in London, because they can liaise with the Treasury, the Bank of England, that makes sense.
"We would not welcome, and we would strongly oppose any proposal to transfer work or jobs from Newport."
Sir Charlie has previously said the ONS is "maybe not quite such a strong performer" as it once was.
However, more recently, he also said Newport could become a centre of expertise in the field of statistics.
An ONS spokesperson said: "ONS has welcomed the Bean Review as a good opportunity to review our systems and processes for measuring the changing UK economy."
"As the interim report of the review is due to be published shortly, it would not be helpful to speculate about its content.
"We look forward to reading its recommendations when it is published."
Sunday Politics Wales can be seen on BBC One Wales at 11:00 GMT on 29 November.
